The .NET and COM Interoperability Handbook (repost)

This book explains the .NET Framework from the perspective of a COM/COM+ programmer. It compares COM/COM+ and .NET. It also shows readers how to use their existing COM/COM+ components from .NET and how to call .NET components from their Win32/COM applications. This is not the kind of cursory coverage of COM interoperability that is found in most .NET Framework books.
