A lot of people work to make a book of this size. Don't think, just because the authors are listed on the front page, that they conceived every idea in the book. It takes a community.

First, thanks to Chuck Sphar and Randy Davis for the fantastic source material that is the backbone of this book. I learned much just editing the f rst two minibooks for use in this All-in-One. Also, thanks to Katie Feltman and Chris Morris for their editorial expertise.

A number of community members had a huge part in the creation of this book. Carey Payette and Phil Japikse built Book V (about WPF) basically from the goodness of their hearts, and I couldn't have completed it without them — my WPF skills aren't worth writing about. These two get the award for Biggest Contribution, and I thank them both.

The developers at Information Control Corporation were also essential in formulating the initial scope of this book and then fact-checking the details. Steve Webb, Stephen Giff n, John Hannah, Larry Beall, Michael Birchmeyer, and Azher Muhammad all had a big part, especially in the information related specif cally to C# 4.0. Thanks to them and all the other ICC experts who gave me ideas and tips.

Kevin Pilch-Bisson at Microsoft provided some C# clarity via Twitter throughout the scope of this book. Steve Andrews provided the structure for the T4 chapter in Book IV. Mads Torgerson reviewed the table of contents, and I thank him for the "It looks delicious" phrase, which I think was my most quoted phrase of the year.

Lars Corneliussen provided a few choice pointers for the book, and Julie Lerman's Entity Framework writing was the basis of my own additions to the ADO.NET chapter.

As always, thanks to my wife, Gabrielle, for her support. Sometimes I just can't believe how lucky I am.
