For those who are new to Visual Studio Async, it extends Visual Studio 2010 and provides streamlined syntax for asynchronous development in C# and Visual Basic.
Microsoft recently released a Async CTP SP1 refresh which now includes Visual Studio 2010 SP1 compatibility, APIs for Windows Phone 7 development, and a new EULA with updates regarding usage in production environments. It is compatible with non-English installations of Visual Studio and with Visual Studio Express.
For ASP.NET MVC 3 devs, you can now program in ASP.NET MVC 3.0 as well as use the Aysnc CTP.
