Query: Not the robust book you may be looking for

One of the great benefits of using C# is the ability to use the many built in methods. This book covers very few of them. It doesn't even cover the common ones like Math and DateTime. If you're looking for a book to cover fundamental C programming, this may work. If you're looking for an introduction to the new features and methods within C# specifically, this ISN'T it.
