Just saw this on the feeds this morning. ASP.Net MVC Framework on Code Plex. I was the 89th person to download :D

Scott Guthrie blogged about it here, interesting thing is the following comment.

Note: the license doesn't enable you to redistribute your custom binary version of ASP.NET MVC (we want to avoid having multiple incompatible ASP.NET MVC versions floating around and colliding with each other).  But it does enable you to make fixes to the code, rebuild it, and avoid getting blocked by an interim bug you can't work around.

I totally agree with this, however this could be a very interesting thing to see by stopping people releasing their own versions out into the wild as part of frameworks.

One thing you'll notice is that not all of the source is released, they still reference System.Web.Routing and System.Web.Abstractions binaries, but it's a fantastic start.

I love how Microsoft are being so much more forthcoming with source code now which will give developers a better chance at seeing something built in a better way. I wish they would release their unit tests with it as well. Even as a seperate project that would be a great thing as I feel that so many projects that release source code don't include enough unit tests.
