Murach's ADO.NET 3.5, LINQ,
and the Entity Framework with VB 2008
An introduction to LINQ
In this chapter, you'll learn the basic skills for using
LINQ, a feature introduced in .NET 3.5. LINQ provides a way
for you to query a data source using constructs that are built
into the Visual Basic language. That way, you can use the
same language to work with a variety of data structures, from
datasets to databases to XML documents.
