Murach's ADO.NET 3.5, LINQ,
and the Entity Framework with C# 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 C# language. That way, you can use the
same language to work with a variety of data structures, from
datasets to databases to XML documents.
To see how well this book works, you can download
this chapter and try it out for yourself.
