Introduction
When we say Language Integrated Query, we might think that it is already integrated into the programming language, just as we write SQL queries in our application. So what is the difference or additional features that we are going to get in LINQ? How is LINQ going to make our programming life easier? Also, I am sure that we all want to know how the new feature, LINQ, is making use of the other new features of C# 3.0. We'll see many of those in this book.

LINQ Architecture
Language Integrated Query is a new feature in Visual Studio 2008 that extends the query capabilities, using C# and Visual Basic. Visual Studio 2008 comes with LINQ provider assemblies that enable the use of Language Integrated Queries with different data sources such as in-memory collections, SQL relational database,
ADO.NET Datasets, XML documents and other data sources.
In Visual Studio 2008, Visual C# and Visual Basic are the languages that implement the LINQ language extensions. The LINQ language extensions use the new Standard Query Operators API, which is the query language for any collection that implements IEnumerable. It means that all collections and arrays can be queried using LINQ. The collections classes simply needs to implement IEnumerable, to enable it for LINQ to query the collections.
