ACKNOWLEDGMENTS
WHEN YOU AUTHOR A BOOK and you get to the process of writing any acknowledgments it is a very
good day. It means you are nally at the end of a very long journey that has many ups and downs.
From late nights working through coding issues, to scouring the web for any new information on
the topics you are trying to write about, getting here requires a lot of help. First and foremost, I
want to thank Maureen Spears for once again leading me through this journey and keeping me
sane when deadlines were missed or things just didn’t work the way I wanted them to. I also need to
thank Mary James for keeping all of us on track and taking care of the various project management
details of which there were many, given the number of authors involved. Finally, I want to thank
Paul Reese who initiated this entire process quite some time ago and got the entire ball rolling!
—N L
THANKS TO MY WIFE for her love and support throughout this project, and thanks also to my man-
agers, Leslie Pickering and Matt Thompson, for their support in writing this book. Windows 8 has
been completely re-imagined, as has the associated developer platform. As such, I owe a debt of
gratitude to numerous people within Microsoft’s Developer Platform & Evangelism (DPE) team, the
Developer Division, as well as the Windows team. Their time and expertise was invaluable as the
book was researched and written. Thanks to Jon Box and Kevin Ashley for their attention to detail
during the technical edit, and a special thank you to Mary James and Maureen Spears at Wiley.
—D H
THANKS TO OLGA for all her support and love, and her family. Thanks to my mother Vera and my
father Gregory; your dedication to Physics will always be my inspiration. Special thanks to Warren
Wilbee and the team at Microsoft—all of you made many dreams possible.
