I know I am a little bit behind in annoucing this. Anyways, if you don't know about it already, Rotor 2.0 (aka Microsoft Shared Source CLI) is available for download here! Now, when you are writing your CLR 2.0 application, and want to debug into the BCL, you can! If you want to know what went into implementing Generics, Nullable Types... you can now just simply debug it and see!
I am curious to know whether any of our implementation is a surprise to anyone. :)
