ASP.NET 4.0 Features
Web.config File Minification
The web.config file by default will contain lot of xml tags, now in the ASP.NET 4 they can be either empty or can contain only one line
<compilation targetFramework="4.0" />
Auto-Start Web Applications
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.
A new scalability feature named auto-start that directly addresses this scenario is available when ASP.NET 4 runs on IIS 7.5 on Windows Server 2008 R2. The auto-start feature provides a controlled approach for starting up an application pool, initializing an ASP.NET application, and then accepting HTTP requests.
Permanently Redirecting a Page
ASP.NET 4 adds a new RedirectPermanent helper method that makes it easy to issue HTTP 301 Moved Permanently responses
Expanding the Range of Allowable URLs
ASP.NET 4 introduces new options for expanding the size of application URLs. Previous versions of ASP.NET constrained URL path lengths to 260 characters (based on the NTFS file-path limit). In ASP.NET 4, you have the option to increase (or decrease) this limit as appropriate for your applications, using two new httpRuntime configuration attributes.
In ASP.NET 4, a new attribute in the compilation element of the Web.config file lets you target the .NET Framework 4 and later.
New Features in the Microsoft Ajax Library
The Microsoft Ajax Library is being released independently of ASP.NET 4 as an open-source and fully supported product.
The Microsoft Ajax Library includes a client-script loader. The client-script loader loads all scripts that are required by a client component or control automatically and executes the scripts in the right order.
ASP.NET Chart Control
The ASP.NET Chart control expands the data-visualization offerings in the .NET Framework. Using the Chart control, you can easily create ASP.NET pages that have intuitive and visually compelling charts for complex statistical or financial analysis.
ASP.NET MVC was introduced as an add-on framework to ASP.NET 3.5 SP1 in March 2009. Visual Studio 2010 will include a preview of ASP.NET MVC 2. When Visual Studio 2010 ships, it will include the RTM version of ASP.NET MVC 2. The version of ASP.NET MVC 2 that is included in ASP.NET 4 Beta 2 includes new features and capabilities.
