Earlier today we released the first CTP preview of an “ASP.NET 3.5 Extensions” release that we’ve been working on (click here to read my previous post about our product roadmap).  This release brings additional runtime functionality to ASP.NET and .NET 3.5.  You can download it here (if you are using the MVC features also click here to download the MVC Toolkit extras).

Looking forwards to checking it out in more detail!
