LINQ in Action won't be available as a paper book before January, but the e-book is already available in preview, and of course .NET 3.5 and Visual Studio 2008 are there. This is why we are now able to publish the complete source code for all the samples included in the book (this includes updated source code for LINQ to Amazon). This download is available for free. All the examples contained in the book and sample projects are included in both C# and VB.NET.
Feel free to download the source code even if you don't own the book (yet) and provide feedback in the book's forum.
