Rotor Design Documentation Please!

Hello All,
I would like learn how exactly .NET framework runs on Win32. I thought I got a break with SSCLI 2.0 (Rotor), but the documentation on how exactly the various components of CLR i.e. VM, JIT etc work is not available. I have built the Rotor but cannot seem to make sense of the enormous code.

On the same hand I do not find a good book which describes how .NET components (CLR in perticular) interact with Win32. So please help me on either or both.

Thanks a lot in Advance.

Ok I think I got my answer elsewhere, thanks anyway. Interested can refer to this book Shared Source CLI Essentials
