Introduces C# 3's lambda expressions and expression trees in an easy-to-understand way, and describes their benefits and uses. Also touches on anonymous delegates.

Learn about some of the new features in C# 3.0 including automatic properties, collection initializers, extension methods, lambda expressions and anonymous types.

C# 3.0 includes a few syntactical additions to the language. For the most part, Microsoft added these language additions to support Language Integrated Query (LINQ). These features include (but are not limited to) lambda expressions, extensions methods, anonymous types, implicitly typed local variables, automatic properties, and object initializers.

Visual Basic (in some of its forms) has always been Microsoft’s choice in dynamic quarter. With the latest release of Visual Basic 9.0 (comes with Visual Studio 2008), dynamic features of VB have been further improved. So, in VB 9.0 you can use extension methods, local variable type inference, lambda expressions and others that make VB even more dynamic. What’s unique about VB is that dynamic behavior can be controlled with a simple directive..
