This tutorial introduces you to the new features of the C# 3.0 programming language. It is broken into four sections, which look at:

• Stuff to do with variables: implicitly typed variables and arrays
• Stuff to do with methods: lambda abstractions and extender methods
• Stuff to do with objects: object initializers and anonymous types
• Stuff to do with logic programming: Linq

While the article introduces C# 3.0 features from scratch, it does depend upon you already having a good knowledge of C#, preferably as far as version 2.0. That is to say, this series is intended as a booster for those who already known C# and want to get to know the new features in version 3.0 rather than a complete C# tutorial.

If you have only worked with C# 1.0, it would probably serve you well to read up on generics, which were introduced in C# 2.0. I will use them in places without any real explanation. Other features in 2.0 are not really needed to follow this tutorial, however. While I refer to anonymous methods, you can learn what they are from this tutorial, since they are essentially a more verbose way of writing C# 3.0 lambda expressions, which I will fully explain.

I hope this tutorial will help you to get acquainted with the exciting new features in C# 3.0, and make your development more productive as a result.
