I just finished reading Foundations of C++/CLI: The Visual C++ Language for .NET 3.5 . I read this book hoping to get a grasp of how to wrap native libraries with C++/CLI. Unfortunately I didn't read the Amazon Editorial review and only chapter 13 covered this topic. The book assumes the reader knows C++ and wants to learn .NET. This made the majority of the book review for me.
This book would probably be good for someone with a C++ background wanting to learn .NET, although if one isn't going to do interop the book recommends using C# instead.
