Microsoft to release full source of the .NET BCL

Holy poop! This is huge!

I know Scott was leading the charge in a general source code cleanup which started some times ago, but it looks like they're nearly done! This is amazing - from within VS 2008 (or your favourite source code editor), you'll be able to seemlessly single-step debug from your own code in that of the .NET framework itself.

Bravo Microsoft! This is an incredibly symbolic step!
