To have a better understanding of what it is and how to program with the Windows 7 Shell Library you can read this article that was written by Yochay Kiriaty and myself.
I have just came back from another Metro Win 7 course that I have given, this time in Budapest Hungary. It was the first time that I have use the new RC materials. We were very busy moving all our slide decks, demo code and Hands On Labs to the RC Version as well as moving many of our samples to use the Windows API Code Pack instead of our Windows 7 Integration Library. The API Code Pack is the official wrapper of Windows 7 features for the .NET developers. There are still some parts that have not been wrapped yet and to use them you will need to continue and use our Windows 7 Integration Libraries. I have fixed the multi-touch wrapper for the RC and it can be downloaded from here. I moved the demo and the HOL of libraries to use the API Code Pack, so I did not need to update the library wrapper of the Windows 7 Integration Library.
