content: Actually I am editing my oppinion after reading this book almost three times now ... The silly typos and mistakes over the book are a fact, however I'd like to say that I really learnt a lot with the book, and overall found it very useful.I missunderstood the focus of the book, and expected more of a "how to do" book, when really it is a logical and structured list (withouth to going into too much depht) of the .NET Frameworks features. After reading simpler books, and with a bit more experience developing in .NET, I actually went back to read it again and found it very very useful.In my oppinion a lof of people commit the same mistake as I did, and expect more of a learning book, than a proper study guide.
