ASP.NET MVC Source Code Released
ScottGu has just announced the release of the ASP.NET MVC Source Code. You can download the code from CodePlex. It is important to note that this does not mean MVC will be open source (or that it won’t be), just that they are sharing the code during development so that we do not need to wait for their releases to correct bugs locally. So while you can create a custom implementation, you cannot distribute it, and I wouldn’t want to rely on it.
