This is a book about Windows programming with Visual Studio, not a pure C# tutorial. That means it includes an introduction to the key Visual Studio tools as well as C# programming. This makes sense to me since most people will be using these tools.

This is not a book for purists. It covers a wide range of topics, and it cannot possibly be comprehensive and detailed. On the other hand, if you work through the book and build all the examples you will have a good grasp both of programming essentials and of what you can do with today's Windows programming tools.
