This book has at least 10 authors and is fun to read for the first few chapters. Then I really got annoyed to read the same things over and over again and at the same time I missed some more in depth explanations. A lot is done with the framework itself. This is probably due to the very early delivery date of the book. Though I really enjoyed the C# example (game of life) I think you be better served with Hollis, Lhotka "VB.Net Programming". Also there seem to be quite a few other books out by now.
