LINQ to SQL (Part 9 - Using a Custom LINQ Expression)

Scott Guthrie continues his series of blog posts that cover LINQ to SQL. "LINQ to SQL is a built-in O/RM (object relational mapper) that ships in the .NET Framework 3.5 release, and which enables you to model relational databases using .NET classes. You can use LINQ expressions to query the database with them, as well as update/insert/delete data."
