This book is built on the beta of version 3.5 of the .NET framework. Since LINQ is a subset of the language enhancements made to
.NET 3.5, the author chose to cover some of them also like Local Type Inference, kinda cool but I think it will lead to sloppy code.
Overall I would say go out and get the book since .NET 3.5 is here.
