A Good book to learn C# libraries

I'm comming as a C++ programmer. I know how to handle quite a bit of Win API with C++. But when it comes to C#, it's plathora of libraries are making me confused. The things I did with with Win API with C++, eludes me when I try to do them with C#. So, I need a better grip of C#.net libraries that interacts with Win API. Can you recommend a good book that shows you how to handle the Win API with C#? I'm looking for a book like the good old classic "Windows 2000 API & COM+ Programming" by Ben Forta.

Thanks.
