Visual Studio Asynchronous Programming

Visual Studio Async is available in the Visual Studio 2012 Release Candidate. It provides streamlined language syntax for asynchronous development in C# and Visual Basic.

Visual Studio 2012 Release Candidate

Download the Visual Studio 2012 RC with new language support in C# and Visual Basic, along with .NET 4.5 APIs for asynchronous development.

If your Visual Studio 2012 RC project needs to target Silverlight 5 or .NET Framework 4.0, you can use the Async language support by downloading the Async Targeting Pack for Visual Studio 2012. This pack is not required for projects targeting .NET Framework 4.5 or .NET for Metro style apps.
