//liveVirtualacademy2011/ core ASP.NET Core Services forms Asynchronously reading and writing HTTP requests and responses ASP.NET 4.5 Developer Preview can read, write, and flush a stream asynchronously. 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.

//liveVirtualacademy2011/ forms ASP.NET Web Forms related Model binders Web Forms now supports model binding, which lets you bind data controls directly to data-access methods. Strongly typed binding expressions You can now write strongly typed, two-way data-binding expressions in Web Forms data controls, instead of using Bind or Eval expressions. Unobtrusive JavaScript for validation obtrusive validation moves the code for client-side validation into a single external JavaScript file, which makes pages smaller and faster to load HTML encoded data-binding expressions New syntax lets you encode HTML output in page markup. 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 , tel, url, and search in Web Forms pages.

//liveVirtualacademy2011/ versions Multi-Version Support iis Enhancements to ASP.NET Multi-Targeting.NET Framework Multi-Targeting for ASP.NET Web Projects ASP.NET Side-by-Side Execution Overview Host Web Applications That Use Different Versions on the Same Server Deploy Web Projects Targeted for Earlier Versions Working with ASP.NET Applications in Either VS 2010 or VS 2011 Open and work with Visual Studio 2010 projects in Visual Studio 11 Developer Preview and vice-versa, without converting the project to a different format

//liveVirtualacademy2011/ iis IIS Express Does not run as a service It does not run as a service or require administrator user rights in order to perform most tasks.
