The ASP.NET 4.5 RC new features are listed. ASP.NET 4.5 RC includes Support for new HTML5 form types, model binders, unobtrusive JavaScript, WebSockets protocol, asynchronous modules and handlers and many more.
Today I was going through the new features of the .NET Framework 4.5; one of them I found is especially good for ASP.NET Developers.
ASP.NET 4.5 RC includes the following new features:
Support for new HTML5 form types.
Support for model binders in Web Forms. I have already posted articles for it:

Definitely more articles on ASP.NET 4.5 are coming from me.
These let you bind data controls directly to data-access methods, and automatically convert user input to and from the .NET Framework data types.
Support for unobtrusive JavaScript in client-side validation scripts.
Improved handling of client scripts through bundling and minification for improved page performance.
Integrated encoding routines from the AntiXSS library (previously an external library) to protect from cross-site scripting attacks.
Support for the WebSockets protocol.
Support for reading and writing HTTP requests and responses asynchronously.
Support for asynchronous modules and handlers.
Support for the Content Distribution Network (CDN) fallback in the ScriptManager control.
