.NET 3.5 introduces significant updates to the C# and VB programming languages, many of which are specifically used to enable Language Integrated Query (LINQ). This course begins by detailing each of these new language features (including extension methods and lambda expressions). Once the foundation has been laid, students will learn to build query expressions using LINQ query operators and the underlying LINQ object model. The remainder of the class will examine how to apply these query expressions to object containers, relational databases and XML documents.
