I'm not sure how many of you out there are aware of the ASP.NET Futures section of the ASP.NET website.  Here's the description of the section from the website:

...contains an early developer preview of features providing a wide range of new functionality for both ASP.NET and Silverlight. The Futures release includes early experimental versions of features currently being considered for future versions of ASP.NET and the .NET Framework.

The May 2007 Release contains the following components:

  • ASP.NET AJAX Futures
  • Silverlight Controls for ASP.NET
  • Dynamic Data Controls for ASP.NET
  • ASP.NET Application Services
  • Dynamic Languages Support for ASP.NET (sans IronRuby, sorry!)

If youwant to find out more, check out the quickstarts or download the binaries!  I know I'm checking out the Silverlight controls, application services and dynamic languages support.
