.NET Framework Library Source Code is now available

Scott Guthrie announced the release of the .NET Framework Source Code!  Scott Hanselman has an excellent post on how to step through the Framework source as well as a caveat on 64-bit installation.  Another other fantastic source on how to actually step into the Framework code is Shawn Burke's blog on configuring Visual Studio for Debug.  You will need the Visual Studio 2008 QFE for this.
