From MSDN: "The LINQ Project is a codename for a set of extensions to the .NET Framework that encompass language-integrated query, set, and transform operations. It extends C# and Visual Basic with native language syntax for queries and provides class libraries to take advantage of these capabilities."
You'll find lots over at the MSDN Linq Project Site as well as the LINQ General Forum.

LINQ and Functional Programming
Anders Hejlsberg, the chief architect of C#, describes the next release of Visual Studio, code-named Orcas. The video explores functional programming and the ways LINQ simplifies how we write database and XML queries in C# and VB.

LINQ to XML
LINQ to XML was developed with Language-Integrated Query over XML in mind and takes advantage of standard query operators and adds query extensions specific to XML.

How do I? Videos on LINQ
- How Do I: LINQ to SQL: Overview - New language features for C# and VB support data access directly from code, without writing SQL. This video shows the minimum steps to use LINQ (Language Integrated Query) to query, update, add and delete rows from the Northwind database.
- How Do I: LINQ to SQL: Data Model - LINQ to SQL relies on an object-to-relational model set of classes that map to your database tables. Visual Studio 2008 includes a visual ORM design surface that maps these tables to code.
- How Do I: LINQ to SQL: Querying the Database - This video shows how to query a database with LINQ, the underlying SQL with a query visualizer, databinding to ASP.NET controls and record paging.
- How Do I: LINQ to SQL: Updating the Database - In this video I demonstrated how to create, update and delete records through LINQ, simple transactions, updates across relationships, and custom column and row validation.
- How Do I: LINQ to SQL: LinqDataSource - The new asp:LinqDataSource control .NET 3.5 makes binding to UI elements easy. In fact, no code was written or harmed in the making of this video. Query, update, delete, paging, sorting, all done through LINQ and the LinqDataSource.
- How Do I: LINQ to SQL: Custom LinqDataSource - The LinqDataSource control can be customized declaritively, as shown in Part 5, or through code by handling the Selecting method.
- How Do I: LINQ to SQL: Using Stored Procedures - Using existing stored procedures and functions is easy with LINQ. We simply drag the stored procedures onto the O/R mapping surface and call them from the generated Data Context object.
