This lets you send data to a client incrementally without tying up operating system threads. Support for reading unvalidated request data when request validation is enabled ASP.NET 4.5 Developer Preview provides ways to read unvalidated request data so that you can allow users to pass markup for selected fields or pages. Support for WebSockets protocol Methods in the new WebSockets namespace provide support for WebSockets protocol, which lets you read and write both string and binary data. Bundling and minification of client scripts ASP.NET 4.5 Developer Preview uses bundling (which combines separate JavaScript files for faster loading) and minification (which reduces the size of JavaScript and CSS files by removing unneeded characters). Support for asynchronous modules and handlers The new await and async keywords make it easier to write asynchronous HTTP modules and asynchronous HTTP handlers. Integrated Anti-XSS encoding routines Anti-XSS (cross-site scripting) core encoding routines have been integrated into ASP.NET 4.5 Developer Preview. These were previously available only as an external library.

Improved paging in the GridView control The new AllowCustomPaging and VirtualItemCount properties of the GridView control let you customize paging functionality Support for HTML5 form types You can use HTML5 elements like email, tel, url, and search in Web Forms pages.
