Intertech's Complete LINQ course is now combined with the Advanced C# course.

The C# and VB programming languages support a number of language features specifically used to enable Language Integrated Query (LINQ). Intertech’s Complete LINQ begins by detailing each of these language constructs (including extension methods and lambda expressions). Once the foundation has been laid, attendees 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, XML documents and in parallel using PLINQ.

If you are interested in learning additional .NET 3.0 / 3.5 technologies, you may wish to view Intertech’s Complete WPF, Complete WCF and Complete WF classes.
