After we published the code samples for LINQ in Action's first chapters in LINQPad a few weeks ago, the samples of three more chapters have just been added. These chapters cover LINQ to XML. Thanks Jim for doing the additional conversion.
Do you know LINQPad? It's a really simple but great tool for testing LINQ queries. Not only that, but it can be used to test all kinds of C# and VB code snippets.
