As Scott Guthrie has stated, Microsoft is hoping to release the first public CTP of the ASP.NET MVC Framework tomorrow. This is very exciting.
If you are interested, you can listen to a podcast Craig Shoemaker recorded with me on the ASP.NET MVC Framework.
Also, there is a new open source project forming. It’s mvccontrib. You can go there through this link. There is no release yet (or code), but with the CTP going public, this project is being kicked off, and we are looking for people interested in submitting patches. Show enough interest by submitting multiple patches, and we’ll make you a committer (that’s the way open-source works).
