Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

The Visual Studio Async CTP (Version 3) extends Visual Studio 2010, providing a new, streamlined syntax for asynchronous development.

• The original Async CTP from PDC 10 brought asynchronous programming to C# and Visual Basic in Visual Studio 2010. This update brings the following:
  • Compatible with Visual Studio 2010 SP1, which is now required.
  • Compatible with non-English installations of Visual Studio and with Visual Studio Express.
  • Compatible with Silverlight 5.
  • Compatible with Windows Phone SDK 7.1 (Mango).
  • Compatible with Roslyn CTP
  • Includes various bug-fixes and changes, detailed in the Readme and documentation.
  • Includes a new EULA for production use. Note - This license does not constitute encouragement for you to use the CTP for your production code. The CTP remains an unsupported and use-at-your-own-risk Technology Preview. However, we’ve received many requests from developers to use the CTP for production code, and so have changed the license to allow that.
