Query: Out of date

Sadly to say, even though this is a newly released book, with the release of .NET beta 2, this book is already woefully out of date. The examples in the book and downloaded from the WROX simply do not work at all. So much has changed with the Beta 2 release of .NET that literally every example I have worked with does not work. This is not to say that a month ago or more, this book was a great value -- it probably was. But, today, I have found that this book is not usable. In fact, if you're learning coding syntax from this book, you'll be very surprised as to how much has already changed. Save your money and sanity and wait. After all, there's no reason to learn syntax that is no longer used.
