Query: A Waste of Money

Do NOT get this book. It is a sham. It is unfortunate that I have to say that because I LOVE Wrox books. I have to say this is the first Wrox book I have ever been dissapointed with. There is nothing of use in this book. The examples are useless, too short and not explained at all. You want to learn C#? Just get the free Beta and go through the tutorials included in the MSDN package - they're really good.
