ACKNOWLEDGMENTS
I ’ VE ALWAYS BEEN A MOBILE ENTHUSIAST, so when the opportunity came about to write one of
the fi rst books to be published on Windows Phone, I jumped at it, not quite envisaging how much
of a challenge it would be. In the months since the early versions of the developer tools were made
available, a great deal changed, often causing whole sections of the book to be completely rewritten. I can’t say how grateful I am to my beautiful Cynthia. Without your unquestioning support and
understanding, I would have never been able to complete this book.
The team at Wrox has been amazing to work with. Their attention to detail and ability to address
even the most challenging aspects of this book have been a lifesaver — especially Paul Reese, Adaobi
Obi Tulton, and the editors who worked on producing this book.
I also extend a big thank you to the Windows Phone team at Microsoft — especially Peter Torr and
Anand Iyer, whose willingness to answer my questions saved hours of experimentation, and Dave
Glover (DPE Australia), who provided an invaluable sounding board for issues and ideas I came
across while writing.
Lastly, I thank my co -author Christopher for sharing his knowledge of multiple mobile platforms
to make sure we addressed issues that were relevant to developers wanting to build applications for
Windows Phone.
—Nick Randolph
I WOULD LIKE TO THANK MY CO-AUTHOR Nick for giving me the opportunity to collaborate on writing this book with him. His passion and in-depth knowledge of multiple modern technologies made
coming up to speed with Windows Phone 7 a breeze. Nick was also very accommodating when it
came to adapting to challenges that came up along the way, such as a magnitude 7.1 earthquake that
occurred within my hometown of Christchurch, New Zealand near the end of the process.
Closer to home, without the patience, reassurance and support of my partner, Michele, I would
never have made it to the end.
Lastly I would like to thank the team at Wrox who has been extremely easy to work with. Their
clear explanation of expectations and quality of feedback has been truly awe-inspiring. Thank you
to Paul Reese, Adaobi Obi Tulton, and the various editors who contributed to making this book
what it is today.
