ACKNOWLEDGMENTS
I WOULD LIKE TO THANK THE ENTIRE TEAM AT WROX, especially Kevin Kent, our Senior Project
Editor, and Bob Elliott, our Executive Editor, who kept this book on schedule on a tight timeline.
You guys really pulled the team together to make this happen. Thank you. I would recommend
Kevin for Project Editor of the Year if there was such an award. I’d also like to thank my two awe-
some co-authors, Bill and Devin. It was a pleasure working with you on the book, and I hope we
can do more in the future. And last but not least, Todd Snyder, Matt Van Horn, Stephen Zaharuk,
Craig Selbert, Mihail Mateev, Shawn Anderson, David Kelley, and Grant Hinkson — you guys
wrote chapters and gave technical guidance, and without you, this book wouldn’t have the backbone
that it does. Thanks for the hard work in making this book a reality.
— Jason Beres
THANKS TO KEVIN KENT, BOB ELLIOTT, AND JIM MINATEL for the opportunity to work on such a
great book. I also want to thank my co-authors who have also been very longtime friends of mine
and guys that have been making this .NET journey with me since the first days. I would also like
to thank my family for putting up with another writing project (as this takes away many weekends
from their time with me). Thank you, Tuija, Sofia, Henri, and Kalle!
— Bill Evjen
THANKS TO JIM MINATEL, BOB ELLIOT, KEVIN KENT, PAUL REESE, and everyone at Wrox for helping us
