LINQ
Short for Language INtegrated Query, LINQ is set of classes added to the .NET Framework 3.5 along with language enhancements added to C# 3.0 and Visual Basic 9, the versions of the language that ship with Visual Studio 2008. LINQ adds a rich, standardized query syntax as a first-class citizen in .NET programming languages that allows developers to interact with any type of data.
