I realize this is a topic that would requires several thousand page books, so are there a few keywords I should search for when looking for a book on amazon? I've been using COM for a few months and I am transitioning to the .NET Framework. It appears that COM is dead in the new framework. What has replaced it? Is there a new viable COM substitute offered by .NET?? I'm reading "Programming .NET" by author Jeff Prosise and he doesn't get into the COM topic except for a few blurbs late in the book.
