Bruce Eckel and coauthor Jaime King have posted a sample of their upcoming book: C# Query Expressions and 3.0 Features

From the authors:

It's become more common for authors to offer a few pages or sometimes a chapter of their text to the public as a means of marketing. Our aim is to not only provide a sample, but also a useful stand-alone text. By itself, this sample provides any C# 2.0 programmer a foundation in C# 3.0.
