ASP .NET 4 Core Services

ASP.NET 4 introduces many features that improve core ASP.NET services such as output caching and session state storage.

Extensible Output Caching

Since ASP.NET 1.0 was released, output caching has enabled developers to store the generated output of pages, controls, and HTTP responses in memory. On subsequent Web requests, ASP.NET can serve content more quickly by retrieving the generated output from memory instead of regenerating the output from scratch. However, this approach has a limitation — generated content always has to be stored in memory. On servers that experience heavy traffic, the memory requirements for output caching can compete with memory requirements for other parts of a Web application.

ASP.NET 4 adds extensibility to output caching that enables you to configure one or more custom output-cache providers. Output-cache providers can use any storage mechanism to persist HTML content. These storage options can include local or remote disks, cloud storage, and distributed cache engines.

Output-cache provider extensibility in ASP.NET 4 lets you design more aggressive and more intelligent output-caching strategies for Web sites. For example, you can create an output-cache provider that caches the "Top 10" pages of a site in memory, while caching pages that get lower traffic on disk. Alternatively, you can cache every vary-by combination for a rendered page, but use a distributed cache so that the memory consumption is offloaded from front-end Web servers.

Prealoading Web Applications

Some Web applications must load large amounts of data or must perform expensive initialization processing before serving the first request. In earlier versions of ASP.NET, for these situations you had to devise custom approaches to "wake up" an ASP.NET application and then run initialization code during the Application_Load method in the Global.asax file.

To address this scenario, a new application preload manager (autostart feature) is available when ASP.NET 4 runs on IIS 7.5 on Windows Server 2008 R2. The preload feature provides a controlled approach for starting up an application pool, initializing an ASP.NET application, and then accepting HTTP requests. It lets you perform expensive application initialization prior to processing the first HTTP request. For example, you can use the application preload manager to initialize an application and then signal a load-balancer that the application was initialized and ready to accept HTTP traffic.

Permanently Redirecting a Page

Content in Web applications is often moved over the lifetime of the application. This can lead to links to be out of date, such as the links that are returned by search engines.

In ASP.NET, developers have traditionally handled requests to old URLs by using the Redirect method to forward a request to the new URL. However, the Redirect method issues an HTTP 302 (Found) response (which is used for a temporary redirect). This results in an extra HTTP round trip.

Session State Compression

By default, ASP.NET provides two options for storing session state across a Web farm. The first option is a session state provider that invokes an out-of-process session state server. The second option is a session state provider that stores data in a Microsoft SQL Server database.

Because both options store state information outside a Web application's worker process, session state has to be serialized before it is sent to remote storage. If a large amount of data is saved in session state, the size of the serialized data can become very large.

ASP.NET 4 introduces a new compression option for both kinds of out-of-process session state providers. By using this option, applications that have spare CPU cycles on Web servers can achieve substantial reductions in the size of serialized session state data.

You can set this option using the new compressionEnabled attribute of the sessionState element in the configuration file. When the compressionEnabled configuration option is set to true, ASP.NET compresses (and decompresses) serialized session state by using the .NET Framework GZipStream class.

ASP .NET 4 Web Forms

Web Forms has been a core feature in ASP.NET since the release of ASP.NET 1.0. Many enhancements have been in this area for ASP.NET 4, such as the following:

- The ability to set meta tags.
- More control over view state.
- Support for recently introduced browsers and devices.
- Easier ways to work with browser capabilities.
- Support for using ASP.NET routing with Web Forms.
- More control over generated IDs.
- The ability to persist selected rows in data controls.
- More control over rendered HTML in the FormView and ListView controls.
- Filtering support for data source controls.
- Enhanced support for Web standards and accessibility

Setting Meta Tags with the Page.MetaKeywords and Page.MetaDescription Propperties

Two properties have been added to the Page class: MetaKeywords and MetaDescription. These two properties work like the Title property does, and they can be set in the @ Page directive.

Enabling View State for Individual Controls

A new property has been added to the Control class: ViewStateMode. You can use this property to disable view state for all controls on a page except those for which you explicitly enable view state.

View state data is included in a page's HTML and increases the amount of time it takes to send a page to the client and post it back. Storing more view state than is necessary can cause significant decrease in performance. In earlier versions of ASP.NET, you could reduce the impact of view state on a page's performance by disabling view state for specific controls. But sometimes it is easier to enable view state for a few controls that need it instead of disabling it for many that do not need it.

Support for Recently Introduced Browsers and Devices

ASP.NET includes a feature that is named browser capabilities that lets you determine the capabilities of the browser that a user is using. Browser capabilities are represented by the HttpBrowserCapabilities object which is stored in the HttpRequest..::.Browser property. Information about a particular browser's capabilities is defined by a browser definition file. In ASP.NET 4, these browser definition files have been updated to contain information about recently introduced browsers and devices such as Google Chrome, Research in Motion BlackBerry smart phones, and Apple iPhone. Existing browser definition files have also been updated.

The browser definition files that are included with ASP.NET 4 are shown in the following list:

- blackberry.browser
- chrome.browser
- Default.browser
- firefox.browser
- gateway.browser
- generic.browser
- ie.browser
- iemobile.browser
- iphone.browser
- opera.browser
- safari.browser

A New Way to Define Browser Capabilitie

ASP.NET 4 includes a new feature referred to as browser capabilities providers. As the name suggests, this lets you build a provider that in turn lets you write custom code to determine browser capabilities.

In ASP.NET version 3.5 Service Pack 1, you define browser capabilities in an XML file. This file resides in a machine-level folder or an application-level folder. Most developers do not need to customize these files, but for those who do, the provider approach can be easier than dealing with complex XML syntax. The provider approach makes it possible to simplify the process by implementing a common browser definition syntax, or a database that contains up-to-date browser definitions, or even a Web service for such a database.

Routing in ASP .NET 4

ASP.NET 4 adds built-in support for routing with Web Forms. Routing is a feature that was introduced with ASP.NET 3.5 SP1 and lets you configure an application to use URLs that are meaningful to users and to search engines because they do not have to specify physical file names. This can make your site more user-friendly and your site content more discoverable by search engines.

Setting Client IDs

The new ClientIDMode property makes it easier to write client script that references HTML elements rendered for server controls. Increasing use of Microsoft Ajax makes the need to do this more common. For example, you may have a data control that renders a long list of products with prices and you want to use client script to make a Web service call and update individual prices in the list as they change without refreshing the entire page.

Typically you get a reference to an HTML element in client script by using the document.GetElementById method. You pass to this method the value of the id attribute of the HTML element you want to reference. In the case of elements that are rendered for ASP.NET server controls earlier versions of ASP.NET could make this difficult or impossible. You were not always able to predict what id values ASP.NET would generate, or ASP.NET could generate very long id values. The problem was especially difficult for data controls that would generate multiple rows for a single instance of the control in your markup.

Persisting Row Selection in Data Controls

The GridView and ListView controls enable users to select a row. In previous versions of ASP.NET, row selection was based on the row index on the page. For example, if you select the third item on page 1 and then move to page 2, the third item on page 2 is selected. In most cases, is more desirable not to select any rows on page 2. ASP.NET 4 supports Persisted Selection, a new feature that was initially supported only in Dynamic Data projects in the .NET Framework 3.5 SP1. When this feature is enabled, the selected item is based on the row data key. This means that if you select the third row on page 1 and move to page 2, nothing is selected on page 2. When you move back to page 1, the third row is still selected. This is a much more natural behavior than the behavior in earlier versions of ASP.NET. Persisted selection is now supported for the GridView and ListView controls in all projects.

FormView Control Enhancements

The ListView control, which was introduced in ASP.NET 3.5, has all the functionality of the GridView control while giving you complete control over the output. This control has been made easier to use in ASP.NET 4. The earlier version of the control required that you specify a layout template that contained a server control with a known ID.

Filtering Data with the QueryExtender Control

A very common task for developers who create data-driven Web pages is to filter data. This traditionally has been performed by building Where clauses in data source controls. This approach can be complicated, and in some cases the Where syntax does not let you take advantage of the full functionality of the underlying database.

To make filtering easier, a new QueryExtender control has been added in ASP.NET 4. This control can be added to EntityDataSource or LinqDataSource controls in order to filter the data returned by these controls. Because the QueryExtender control relies on LINQ, but you do not to need to know how to write LINQ queries to use the query extender.

Enhanced Support for Web Standards and Accessibility

Earlier versions of ASP.NET controls sometimes render markup that does not conform to HTML, XHTML, or accessibility standards. ASP.NET 4 eliminates most of these exceptions.

CSS for Controls that Can be Disabled

In ASP.NET 3.5, when a control is disabled (see WebControl..::.Enabled), a disabled attribute is added to the rendered HTML element.

CSS for Validation Controls

In ASP.NET 3.5, validation controls render a default color of red as an inline style. Therefore, ASP.NET 4 does not automatically show error messages in red.

CSS for Hidden Fields Div Element

ASP.NET uses hidden fields to store state information such as view state and control state. These hidden fields are contained by a div element. In ASP.NET 3.5, this div element does not have a class attribute or an id attribute. Therefore, CSS rules that affect all div elements could unintentionally cause this div to be visible. To avoid this problem, ASP.NET 4 renders the div element for hidden fields with a CSS class that you can use to differentiate the hidden fields div from others.

CSS for Table, Image, and ImageButton Controls

By default, in ASP.NET 3.5, some controls set the border attribute of rendered HTML to zero (0).

CSS for UpdatePanel and UpdateProgress Controls

In ASP.NET 3.5, the UpdatePanel and UpdateProgress controls do not support expando attributes. This makes it impossible to set a CSS class on the HTML elements that they render.

Eliminating Unnecessary Outer Tables

In ASP.NET 3.5, the HTML that is rendered for the following controls is wrapped in a table element whose purpose is to apply inline styles to the entire control:

- FormView
- Login
- Password Recovery
- ChangePassword

If you use templates to customize the appearance of these controls, you can specify CSS styles in the markup that you provide in the templates. In that case, no extra outer table is required. In ASP.NET 4, you can prevent the table from being rendered by setting the new RenderOuterTable property to false.

Visual Basic Complier and Language

Auto-Implemented Properties

Auto-implemented properties provide a shortened syntax that enables you to quickly specify a property of a class without having to write code to Get and Set the property.

Collection Initializers

Collection initializers provide a shortened syntax that enables you to create a collection and populate it with an initial set of values. Collection initializers are useful when you are creating a collection from a set of known values, for example, a list of menu options or categories.

Implicit Line Continuation

In many cases, implicit line continuation enables you to continue a statement on the next consecutive line without using the underscore character (_).

Multiline Lambda Expressions and Subroutines

Lambda expression support has been expanded to support subroutines in addition to multiline lambda functions and subroutines.

New Command-Line Option for Specifying a Language Version

The /langversion command-line option causes the compiler to accept only syntax that is valid in the specified version of Visual Basic.

Type Equivalence Support

You can now deploy an application that has embedded type information instead of type information that is imported from a Primary Interop Assembly (PIA). With embedded type information, your application can use types in a runtime without requiring a reference to the runtime assembly. If various versions of the runtime assembly are published, the application that contains the embedded type information can work with the various versions without having to be recompiled.

Dynamic Support

Visual Basic binds to objects from dynamic languages such as IronPython and IronRuby.

Covariance and Contravariance

Covariance enables you to use a more derived type than that specified by the generic parameter, whereas contravariance enables you to use a less derived type. This allows for implicit conversion of classes that implement variant interfaces and provides more flexibility for matching method signatures with variant delegate types. You can create variant interfaces and delegates by using the new In and Out language keywords. The .NET Framework also introduces variance support for several existing generic interfaces and delegates, including the IEnumerable<(Of <(T>)>) interface and the Func<(Of <(TResult>)>) and Action<(Of <(T>)>) delegates.

Integrated Development Environment

Navigate to

You can use the Navigate To feature to search for a symbol or file in source code. You can search for keywords that are contained in a symbol by using Camel casing and underscore characters to divide the symbol into keywords.

Highlighting References

When you click a symbol in source code, all instances of that symbol are highlighted in the document.

For many control structures, when you click a keyword, all of the keywords in the structure are highlighted. For instance, when you click If in an If...Then...Else construction, all instances of If, Then, ElseIf, Else, and End If in the construction are highlighted.

To move to the next or previous highlighted symbol, you can use CTRL+SHIFT+DOWN ARROW or CTRL+SHIFT+UP ARROW.

Generate from Usage

The Generate From Usage feature enables you to use classes and members before you define them. You can generate a stub for any class, constructor, method, property, field, or enum that you want to use but have not yet defined. You can generate new types and members without leaving your current location in code. This minimizes interruption to your workflow.

Generate From Usage supports programming styles such as test-first development.

IntelliSense Suggestion Mode

IntelliSense now provides two alternatives for IntelliSense statement completion: completion mode and suggestion mode. Suggestion mode is used when classes and members are used before they are defined.

Sample Application

Visual Basic includes new sample applications that demonstrate the following features: auto-implemented properties, implicit line continuation, collection initializers, covariance and contravariance, and multiline lambda expressions and subroutines.

Auto-Start Web Applications with ASP.NET 4

Some web applications need to load large amounts of data, or perform expensive initialization processing, before they are ready to process requests.  Developers using ASP.NET today often do this work using the “Application_Start” event handler within the Global.asax file of an application (which fires the first time a request executes).  They then either devise custom scripts to send fake requests to the application to periodically “wake it up” and execute this code before a customer hits it, or simply cause the unfortunate first customer that accesses the application to wait while this logic finishes before processing the request (which can lead to a long delay for them).

ASP.NET 4 ships with a new feature called “auto-start” that better addresses this scenario, and is available when ASP.NET 4 runs on IIS 7.5 (which ships with Windows 7 and Windows Server 2008 R2).  The auto-start feature provides a controlled approach for starting up an application worker process, initializing an ASP.NET application, and then accepting HTTP requests.

Configuring an ASP.NET 4 Application to Auto-Start

To use the ASP.NET 4 auto-start feature, you first configure the IIS “application pool” worker process that the application runs within to automatically startup when the web-server first loads.  You can do this by opening up the IIS 7.5 applicationHost.config file (C:\Windows\System32\inetsrv\config\applicationHost.config) and by adding a startMode=”AlwaysRunning” attribute to the appropriate <applicationPools> entry:

          <applicationPools>
                    <add name =”MyAppWorkerProcess” managedRuntimeVersion=”v4.0” startMode=”AlwaysRunning” />
          </applicationPools>

If you load up the Windows task manager, click the “show processes from all users” checkbox, and then hit save on a startMode attribute change to the applicationHost.config file, you’ll see a new “w3wp.exe” worker process immediately startup as soon as the file is saved.

A single IIS application pool worker process can host multiple ASP.NET applications.  You can specify which applications you want to have automatically start when the worker process loads by adding a serviceAutoStartEnabled="true" attribute on their <application> configuration entry:

          <sites>
                   <site name =”MySite” id=”1”>
                           <application path=”/” serviceAutoStartEnabled=”true” serviceAutoStartProvider=”PreWarmMyCache” />
                   </site>
          </sites>
          <serviceAutoStartProviders>
                   <add name=”PreWarmMyCache” type=”PreWarmCache, MyAssembly” />
          </serviceAutoStartProviders>

The serviceAutoProvider="PreWarmMyCache" attribute above references a provider entry within the config file that enables you to configure a custom class that can be used to encapsulate any "warming up" logic for the application.  This class will be automatically invoked as soon as the worker process and application are preloaded (before any external web requests are received), and can be used to execute any initialization or cache loading logic you want to run before requests are received and processed:

          public class PreWarmCache : System.Web.Hosting.IProcessHostPreloadClient {
                  public void Preload(string[] parameters) {
                          // Perform initialization and cache loading logic here…
                  }
          }

IIS will start the application in a state during which it will not accept requests until your "warming up" logic has completed.  After your initialization code runs in the Preload method and the method returns, the ASP.NET application will be marked as ready to process requests. 

You can optionally combine the new auto-start "warming up" feature with the load-balancing capabilities of the IIS7 Application Request Routing (ARR) extension, and use it to signal to a load-balancer once the application is initialized and ready to accept HTTP traffic – at which point the server can be brought into the web farm to process requests.

Summary

The new "auto start" feature of ASP.NET 4 and IIS 7.5 provides a well-defined approach that allows you to perform expensive application startup and pre-cache logic that can run before any end-users hit your application.  This enables you to have your application "warmed up" and ready from the very beginning, and deliver a consistent high performance experience.

Compacting out-of-Process Session Data

We like using the Session object (We like the Cache object even better). Many developers object to the Session object because it imposes a footprint on the server even when a user isn't requesting a page. In ASP.NET 4 the sessionState tag in the web.config file now has a new attribute called compressionEnabled that causes serialized to data to be automatically compressed. Here's what it looks like:

<sessionState
         compressionEnabled=”true”. . .

Session data is only serialized if you're using a state server (where mode is set to "StateServer") or a database (mode="SqlServer"). But in those scenarios, this option will lower the impact of the user's footprint when storing data in the Session object -- provided you're willing to spend the CPU cycles to compact and un-compact your data.

Permanently Redirecting a Page

It would be wonderful if we never changed the URLs for our pages. However, in the real world that doesn't happen. Pages move around. Rather than let users get 404 errors when requesting a page using a URL that's worked in the past, ASP.NET programmers often put a Response.Redirect in the Page Load of the old page and have that Redirect send the user to the new location of the page.

In ASP.NET 4, you can now use the Response.RedirectPermanent method in the same way. RedirectPermanent issues HTTP 301 messages which signal to the client that this is a permanent redirection. Provided the client recognizes 301 messages, the client will automatically substitute the new URL for the old URL whenever the user requests the old URL, skipping the trip to the old location.

Alternatively, you could use Routing, which eliminates this problem. Implementing routing is much simpler in ASP.NET 4 and I'll cover that topic in a later column.

Control-Level Changes

Probably the most important change to existing controls is invisible: Many controls will be generating different HTML in ASP.NET 4. Partially this is a move to produce HTML that is more complaint with XHTML 4.0; partially it is an effort to produce HTML that CSS authors (i.e. not me) will find easier to style. Overall, there's a sharp reduction in the number of table tags being produced. However, if you have code that's dependent on the old HTML format, you can add this element to your config file to keep the old HTML:

<pages controlRenderingCompatibilityVersion=”3.5”/>

In the past, if you wanted to reduce the size of a page's ViewState, you considered setting the EnableViewState property on the Page to False. However, that disabled ViewState for all the controls on the page, and usually there were some controls that needed the ViewState. The alternative was to disable ViewState on each control where you didn't need it -- typically most of the controls on the page. Now in ASP.NET 4, you can disable ViewState for the Page and set EnableViewStateMode to Enabled on the controls where you actually need ViewState.

Why SEO?

Search engine optimization (SEO) is important for any publically facing web-site.  A large percentage of traffic to sites now comes from search engines, and improving the search relevancy of your site will lead to more user traffic to your site from search engine queries (which can directly or indirectly increase the revenue you make through your site).

Measuring the SEO of your website with the SEO Toolkit

We blogged about the free SEO Toolkit we’ve shipped that you can use to analyze your site for SEO correctness, and which provides detailed suggestions on any SEO issues it finds. 

We highly recommend downloading and using the tool against any public site you work on.  It makes it easy to spot SEO issues you might have in the site, and pinpoint ways to optimize it further.

ASP .NET 4 SEO Improvement

ASP.NET 4 includes a bunch of new runtime features that can help you to further optimize your site for SEO.  Some of these new features include:

- New Page.MetaKeywords and Page.MetaDescription properties
- New URL Routing support for ASP.NET Web Forms
- New Response.RedirectPermanent() method

Below are details about how you can take advantage of them to further improve your search engine relevancy.

Page.MetaKeywords and Page.MetaDescription properties

One simple recommendation to improve the search relevancy of pages is to make sure you always output relevant “keywords” and “description” <meta> tags within the <head> section of your HTML.  For example:

<head runat=”server”>
           <title>My Page Title</title>
           <meta name=”keywords” content=”These, are, my, keywords” />
           <meta name=”description” content=”This is the description of my page” />
</head>

One of the nice improvements with ASP.NET 4 Web Forms is the addition of two new properties to the Page class: MetaKeywords and MetaDescription that make programmatically setting these values within your code-behind classes much easier and cleaner. 

ASP.NET 4’s <head> server control now looks at these values and will use them when outputting the <head> section of pages.  This behavior is particularly useful for scenarios where you are using master-pages within your site – and the <head> section ends up being in a .master file that is separate from the .aspx file that contains the page specific content.  You can now set the new MetaKeywords and MetaDescription properties in the .aspx page and have their values automatically rendered by the <head> control within the master page.

Below is a simple code snippet that demonstrates setting these properties programmatically within a Page_Load() event handler:

void Page_Load(object sender, EventsArgs e)
{
           Page.Title = “Setting the <head>’s <title> programmatically was already supported”;

           Page.MetaDescription = “Now you can set the <head>’s <meta> description too”;
           Page.MetaKeywords = “scottgu, blog, simple, sample, keywords”;
}

In addition to setting the Keywords and Description properties programmatically in your code-behind, you can also now declaratively set them within the @Page directive at the top of .aspx pages.

As you’d probably expect, if you set the values programmatically they will override any values declaratively set in either the <head> section or the via the @Page attribute. 

URL Routing with ASP.NET Web Forms

URL routing was a capability we first introduced with ASP.NET 3.5 SP1, and which is already used within ASP.NET MVC applications to expose clean, SEO-friendly “web 2.0” URLs.  URL routing lets you configure an application to accept request URLs that do not map to physical files. Instead, you can use routing to define URLs that are semantically meaningful to users and that can help with search-engine optimization (SEO).

With ASP.NET 4.0, URLs like above can now be mapped to both ASP.NET MVC Controller classes, as well as ASP.NET Web Forms based pages.  You can even have a single application that contains both Web Forms and MVC Controllers, and use a single set of routing rules to map URLs between them.

Response.RedirectPermanent() Method

It is pretty common within web applications to move pages and other content around over time, which can lead to an accumulation of stale links in search engines.

In ASP.NET, developers have often handled requests to old URLs by using the Response.Redirect() method to programmatically forward a request to the new URL.  However, what many developers don’t realize is that the Response.Redirect() method issues an HTTP 302 Found (temporary redirect) response, which results in an extra HTTP round trip when users attempt to access the old URLs.  Search engines typically will not follow across multiple redirection hops – which means using a temporary redirect can negatively impact your page ranking.  You can use the SEO Toolkit to identify places within a site where you might have this issue.

ASP.NET 4 introduces a new Response.RedirectPermanent(string url) helper method that can be used to perform a redirect using an HTTP 301 (moved permanently) response.  This will cause search engines and other user agents that recognize permanent redirects to store and use the new URL that is associated with the content.  This will enable your content to be indexed and your search engine page ranking to improve.

Below is an example of using the new Response.RedirectPermanent() method to redirect to a specific URL:

Response.RedirectPermanent(“NewPath/ForOldContent.aspx”);

ASP.NET 4 also introduces new Response.RedirectToRoute(string routeName) and Response.RedirectToRoutePermanent(string routeName) helper methods that can be used to redirect users using either a temporary or permanent redirect using the URL routing engine.  The code snippets below demonstrate how to issue temporary and permanent redirects to named routes (that take a category parameter) registered with the URL routing system.

// Issue temporary HTTP 302 redirect to a named route
Response.RedirectToRoute(“Products-Browse”, new { category = “beverages” });

//Issue permanent HTTP 301 redirect to a named route
Response.RedirectToRoutePermanent(“Products-Browse”, new { category = “beverages” } );

You can use the above routes and methods for both ASP.NET Web Forms and ASP.NET MVC based URLs.

Summary

ASP.NET 4 includes a bunch of feature improvements that make it easier to build public facing sites that have great SEO.  When combined with the SEO Toolkit, you should be able to use these features to increase user traffic to your site – and hopefully increase the direct or indirect revenue you make from them.

This topic contains information about key features and improvements in the .NET Framework version 4. This topic does not provide comprehensive information about all new features and is subject to change.

Other new features and improvements in the .NET Framework 4 are described in the following sections:

1. Application Compatibility and Deployment
The .NET Framework 4 is highly compatible with applications that are built with earlier .NET Framework versions, except for some changes that were made to improve security, standards compliance, correctness, reliability, and performance.

The .NET Framework 4 does not automatically use its version of the common language runtime to run applications that are built with earlier versions of the .NET Framework. To run older applications with .NET Framework 4, you must compile your application with the target .NET Framework version specified in the properties for your project in Visual Studio.

The following sections describe deployment improvements.

- Client Profile
The .NET Framework 4 Client Profile supports more platforms than in previous versions and provides a fast deployment experience for your Windows Presentation Foundation (WPF), console, or Windows Forms applications.

- In-Process Side-by-Side-Execution
This feature enables an application to load and start multiple versions of the .NET Framework in the same process. For example, you can run applications that load add-ins (or components) that are based on the .NET Framework 2.0 SP1 and add-ins that are based on the .NET Framework 4 in the same process.

2. Core New Features and Improvements
The following sections describe new features and improvements provided by the common language runtime and the base class libraries.

- Diagnostics and Performance
Earlier versions of the .NET Framework provided no way to determine whether a particular application domain was affecting other application domains, because the operating system APIs and tools, such as the Windows Task Manager, were precise only to the process level. Starting with the .NET Framework 4, you can get processor usage and memory usage estimates per application domain.

You can monitor CPU and memory usage of individual application domains. Application domain resource monitoring is available through the managed and native hosting APIs and event tracing for Windows (ETW). When this feature has been enabled, it collects statistics on all application domains in the process for the life of the process.

- Garbage Collection
The .NET Framework 4 provides background garbage collection. This feature replaces concurrent garbage collection in previous versions and provides better performance.

- Code Contracts
Code contracts let you specify contractual information that is not represented by a method's or type's signature alone. The new System.Diagnostics.Contracts namespace contains classes that provide a language-neutral way to express coding assumptions in the form of preconditions, postconditions, and object invariants. The contracts improve testing with run-time checking, enable static contract verification, and support documentation generation.

- Design-Time-Only Interop Assemblies
You no longer have to ship primary interop assemblies (PIAs) to deploy applications that interoperate with COM objects. In the .NET Framework 4, compilers can embed type information from interop assemblies, selecting only the types that an application (for example, an add-in) actually uses. Type safety is ensured by the common language runtime.

- Dynamic Language Runtime
The dynamic language runtime (DLR) is a new runtime environment that adds a set of services for dynamic languages to the CLR. The DLR makes it easier to develop dynamic languages to run on the .NET Framework and to add dynamic features to statically typed languages. To support the DLR, the new System.Dynamic namespace is added to the .NET Framework.

The expression trees are extended with new types that represent control flow, for example, System.Linq.Expressions..::.LoopExpression and System.Linq.Expressions..::.TryExpression. These new types are used by the dynamic language runtime (DLR) and not used by LINQ.

In addition, several new classes that support the .NET Framework infrastructure are added to the System.Runtime.CompilerServices namespace.

- Covariance and Contravariance
Several generic interfaces and delegates now support covariance and contravariance.

- BigInteger and Complex Numbers
The new System.Numerics..::.BigInteger structure is an arbitrary-precision integer data type that supports all the standard integer operations, including bit manipulation. It can be used from any .NET Framework language. In addition, some of the new .NET Framework languages (such as F# and IronPython) have built-in support for this structure.

The new System.Numerics..::.Complex structure represents a complex number that supports arithmetic and trigonometric operations with complex numbers.

- Tuples
The .NET Framework 4 provides the System..::.Tuple class for creating tuple objects that contain structured data. It also provides generic tuple classes to support tuples that have from one to eight components (that is, singletons through octuples). To support tuple objects that have nine or more components, there is a generic tuple class with seven type parameters and an eighth parameter of any tuple type. 

- File System Enumeration Improvements
New file enumeration methods improve the performance of applications that access large file directories or that iterate through the lines in large files.

- Memory-Mapped Files
You can use memory-mapped files to edit very large files and to create shared memory for interprocess communication.

- 64-Bit Operating Systems and Processes
You can identify 64-bit operating systems and processes with the Environment..::.Is64BitOperatingSystem and Environment..::.Is64BitProcess properties.

- Other New Features
The following list describes additional new capabilities, improvements, and conveniences. Several of these are based on customer suggestions.
1. To upport culture-sensitive formatting, the System..::.TimeSpan structure includes new overloads of the ToString, Parse, and TryParse methods, as well as new ParseExact and TryParseExact methods.

2. The new String..::.IsNullOrWhiteSpace method indicates whether a string is null, empty, or consists only of white-space characters. New overloads have been added to the String.Concat and String.Join methods that concatenate members of System.Collections.Generic..::.IEnumerable<(Of <(T>)>) collections.

3. The String..::.Contract method lets you concatenate each element in an enumerable collection without first converting the elements to strings.

4. Two new convenience methods are available: StringBuilder..::.Clear and Stopwatch..::.Restart.

5. The new Enum..::.HasFlag method determines whether one or more bit fields or flags are set in an enumeration value. The Enum..::.TryParse method returns a Boolean value that indicates whether a string or integer value could be successfully parsed.

6. The System..::.Environment..::.SpecialFolder enumeration contains several new folders.

7. You can now easily copy one stream into another with the CopyTo method in classes that inherit from the System.IO..::.Stream class.

8. New Path..::.Combine method overloads enable you to combine file paths.

9. The new System..::.IObservable<(Of <(T>)>) and System..::.IObserver<(Of <(T>)>) interfaces provide a generalized mechanism for push-based notifications.

10. The System..::.IntPtr and System..::.UIntPtr classes now include support for the addition and subtraction operators.

11. You can now enable lazy initialization for any custom type by wrapping the type inside a System..::.Lazy<(Of <(T>)>) class.

12. The new System.Collections.Generic..::.SortedSet<(Of <(T>)>) class provides a self-balancing tree that maintains data in sorted order after insertions, deletions, and searches. This class implements the new System.Collections.Generic..::.ISet<(Of <(T>)>) interface.

13. The compression algorithms for the System.IO.Compression..::.DeflateStream and System.IO.Compression..::.GZipStream classes have improved so that data that is already compressed is no longer inflated. Also, the 4-gigabyte size restriction for compressing streams has been removed.

14. The new Monitor..::.Enter(Object, Boolean%) method overload takes a Boolean reference and atomically sets it to true only if the monitor is successfully entered.

15. You can use the Thread..::.Yield method to have the calling thread yield execution to another thread that is ready to run on the current processor.

16. The System..::.Guid structure now contains the TryParse and TryParseExact methods.

17. The new Microsoft.Win32..::.RegistryOptions enumeration lets you specify a volatile registry key that does not persist after the computer restarts.

Managed Extensibility Framework

The Managed Extensibility Framework (MEF) is a new library in the .NET Framework 4 that helps you build extensible and composable applications. MEF enables you to specify points where an application can be extended, to expose services to offer to other extensible applications and to create parts for consumption by extensible applications. It also enables easy discoverability of available parts based on metadata, without the need to load the assemblies for the parts.

Parallel Computing

The .NET Framework 4 introduces a new programming model for writing multithreaded and asynchronous code that greatly simplifies the work of application and library developers. The new model enables developers to write efficient, fine-grained, and scalable parallel code in a natural idiom without having to work directly with threads or the thread pool. The new System.Threading.Tasks namespace and other related types support this new model. Parallel LINQ (PLINQ), which is a parallel implementation of LINQ to Objects, enables similar functionality through declarative syntax.

Networking

Networking improvements include the following:

1. Security improvements for Windows authentication in several classes, including System.Net..::.HttpWebRequest, System.Net..::.HttpListener, System.Net.Mail..::.SmtpClient, System.Net.Security..::.SslStream, and System.Net.Security..::.NegotiateStream. Extended protection is available for applications on Windows 7 and Windows Server 2008 R2.

2. Support for Network Address Translation (NAT) traversal using IPv6 and Teredo.

3. New networking performance counters that provide information about HttpWebRequest objects.

4. In the System.Net..::.HttpWebRequest class, support for using large byte range headers (64-bit ranges) with new overloads for the AddRange method. New properties on the System.Net..::.HttpWebRequest class allow an application to set many HTTP headers. You can use the Host property to set the Host header value in an HTTP request that is independent from the request URI.

5. Secure Sockets Layer (SSL) support for the System.Net.Mail..::.SmtpClient and related classes.

6. Improved support for mail headers in the System.Net.Mail..::.MailMessage class.

7. Support for a null cipher for use in encryption. You can specify the encryption policy by using the System.Net..::.ServicePointManager class and the EncryptionPolicy property. Constructors for the System.Net.Security..::.SslStream class now take a System.Net.Security..::.EncryptionPolicy class as a parameter.

8. Credentials for password-based authentication schemes such as basic, digest, NTLM, and Kerberos authentication in the System.Net..::.NetworkCredential class. To improved security, passwords may now be treated as System.Security..::.SecureString instances rather than System..::.String instances.

9. Ability to specify how a URI with percent-encoded values is converted and normalized in the System..::.Uri and System.Net..::.HttpListener classes.

Web

ASP.NET version 4 introduces new features in the following areas:

1. Core services, including a new API that lets you extend caching, support for compression for session-state data, and a new application preload manager (autostart feature).

2. Web Forms, including more integrated support for ASP.NET routing, enhanced support for Web standards, updated browser support, new features for data controls, and new features for view state management.

3. Web Forms controls, including a new Chart control.

4. MVC, including new helper methods for views, support for partitioned MVC applications, and asynchronous controllers.

5. Dynamic Data, including support for existing Web applications, support for many-to-many relationships and inheritance, new field templates and attributes, and enhanced data filtering.

6. Microsoft Ajax, including additional support for client-based Ajax applications in the Microsoft Ajax Library.

7. Visual Web Developer, including improved IntelliSense for JScript, new auto-complete snippets for HTML and ASP.NET markup, and enhanced CSS compatibility.

8. Deployment, including new tools for automating typical deployment tasks.

9. Multi-targeting, including better filtering for features that are not available in the target version of the .NET Framework.

Client

Windows Presentation Foundation
In the .NET Framework 4, Windows Presentation Foundation (WPF) contains changes and improvements in many areas, including controls, graphics, and XAML. 

Data

ADO. NET
ADO.NET provides new features for the Entity Framework, including Persistence-Ignorant Objects, functions in LINQ queries, and Customized Object Layer Code Generation.

Dynamic Data
For ASP.NET 4, Dynamic Data has been enhanced to give you even more power for quickly building data-driven Web sites. This includes the following:

- Automatic validation that is based on constraints that are defined in the data model.

- The ability to easily change the markup that is generated for fields in the GridView and DetailsView controls by using field templates that are part of a Dynamic Data project.

Communications and Workflow

Windows Communication Foundation (WCF) provides messaging enhancements and seamless integration with Windows Workflow Foundation (WF). WF provides improvements in performance, scalability, workflow modeling, and an updated visual designer.

Happy Hosting!

If you're an avid .NET programmer, you are likely aware of what the above title says. Since the birth of multi-core computing, there has been a need for parallel-programming architecture. Now, the multi-core computing has become the prevailing paradigm in computer architecture due to the invention of multi core-processors. By the way, almost every programmer considers Visual Studio 2008 and .NET Framework 3.5 as getting remote and out of the way. To avert its programming market fiasco, recently, Microsoft released the beta versions of .NET Framework 4 and Visual Studio 2010. The main focus fell on .NET 4, yet the labels boasted the advent of parallel-programming. The question is whether there are any advantages (more specifically towards performance) on sticking to existing APIs? This article attempts to briefly answer the question.

.NET 4's Multi-Core processing ability: First of all, the MSDN site shows that the parallel extensions in the .NET 4 , has been improved to support parallel programming, targeting multi-core computing or distributed computing. The support for the Framework has been categorized into four areas like library, LINQ, data structures and diagonastic tools. .NET 4's peers and predecessors lacked the multi-core operable ability. The main criteria like communication and synchronization of sub-tasks were considered as the biggest obstacles in getting a good parallel program performance. But .NET 4's promising parallel library technology enables developers to define simultaneous, asynchronous tasks without having to work with threads, locks, or the thread pool.

Full support for multiple programming languages and compilers: Apart from VB & C# languages, .NET 4 establishes full support for programming languages like Ironpython, Ironruby, F# and other similar .NET compilers. Unlike 3.5, it encompasses both functional-programming and imperative object-oriented programming.

Dynamic language runtime: Addition of the dynamic language runtime (DLR) is a boon to .NET beginners. Using this new DLR runtime environment, developers can add a set of services for dynamic languages to the CLR. In addition to that, the DLR makes it simpler to develop dynamic languages and to add dynamic features to statically typed languages. A new System Dynamic name space has been added to the .NET Framework on supporting the DLR and several new classes supporting the .NET Framework infrastructure are added to the System Runtime Compiler Services.

Anyway, the new DLR provides the following advantages to developers: Developers can use rapid feedback loop which lets them enter various statements and execute them to see the results almost immediately. Support for both top-down and more traditional bottom-up development. For instance, when a developer uses a top-down approach, he can call-out functions that are not yet implemented and then add them when needed. Easier refactoring and code modifications (Developers do not have to change static type declarations throughout the code)

Parallel-diagnostics: Unlike Visual Studio 2008, the new Visual Studio 2010 supports debugging and profiling, extensively. The new profiling tools provides various data views which displays graphical, tabular and numerical information about how a parallel or multiple-threaded application interacts with itself and with other programs. The results enable developers to quickly identify areas of concern, and helps in navigating from points on the displays to call stacks & source codes. If you think only parallel programming abilities and promising capabilities make the MS .NET 4.0 a more promising next generation programming tool, think again! That's not all. There are also a number of enhancements to the Base Libraries for things like collections, reflection, data structures, handling, threading and lots of new features for the web.
