C# 4 is even more expressive and powerful than earlier versions. You can do amazing things with generics, lambda expressions, dynamic typing, LINQ, iterator blocks, and other features - but you first have to learn C# in depth. C# in Depth, Second Edition is a thoroughly revised, up-to-date book that covers the new features of C# 4 as well as Code Contracts. In it, you'll see the subtleties of C# programming in action, learning how to work with high-value features that you'll be glad to have in your toolkit. The book helps readers avoid hidden pitfalls of C# programming by understanding "behind the scenes" issues.
