.Net Framework Library Source Code

Scott Guthrie, a GM in the division I work in (Developer Division) has just made a great post about how Microsoft will be releasing the source code of the .Net Framework libraries along with Visual Studio 2008

I know, I know, the majority of you that develop using one of the .Net techologies use reflector, so this may not seem like a big deal but consider the demo that Scott walks through that shows the integration of debugging, source and symbols.  This is such a win for .Net developers.
