ABOUT THE AUTHORS
NICK LECRENSKI is a developer with 10 years of experience in a wide range of Microsoft
technologies including Visual C++, C#, VB, VB.NET, SQL Server, .NET Framework, ASP.NET,
AJAX, Silverlight, and more. He has a BS in Computer Science and has worked in various fi elds from
biometrics to fi nancial services. He is also the founder and lead developer of MyFitnessJournal.com, a
fi tness training website that currently utilizes Silverlight technology. He is also the author of
Silverlight 4: Problem - Design - Solution, available from www.wrox.com.
KARLI WATSON is an IT contractor and author currently working in London in the fi nancial sector.
For the most part, he immerses himself in .NET (in particular, C#) and has written numerous
books in the fi eld for several publishers. He specializes in communicating complex ideas in a
way that is accessible to anyone with a passion to learn, and he spends much of his time playing
with technology to fi nd new things to teach people. During those (seemingly few) times where he
isn’t doing the previous, Karli is probably wishing he was hurtling down a mountain on a
snowboard or possibly trying to get his novel published. Either way, you’ll know him by his
brightly colored clothes.

ROBERT FONSECA-ENSOR is a software engineer consulting with Infusion (www.infusion.com).

From New Zealand, he currently lives in London. He specializes in user interface development and
has been working with Microsoft Surface, Silverlight, and WPF for the past four years. Rob has a

strong passion for learning new things and then teaching them to others. He enjoys attending and
presenting at .NET user groups so much that he started the Canary Wharf .NET User Group. He
plans to become a university professor “as soon as he gets sick of coding in the real world,” which
isn’t going to happen soon. Rob’s wife is an IOS developer, and together they have built and released
a couple of successful iPhone games. Now that his weekends are writing-free, he plans to churn out
some awesome WP7 games, so watch your back. Rob keeps a blog at www.robfe.com, and has a
twitter account at www.twitter.com/robfe.

ACKNOWLEDGMENTS
I WOULD LIKE TO THANK EVERYONE at Wrox who had a part in helping to get this book to print.
First, I would like to thank my family for supporting me on another book writing endeavor. I would
also like to take the time to thank Paul Reese for giving me the opportunity to work on another
book project and Ginny Munroe, our primary editor, who fought to keep us all on track and on
time, which was no easy task. I would also like to thank Jonathan Marbutt, our technical editor,
for checking all of our code and offering valuable input during the writing process. Finally, I would
also like to thank my co-authors, Karli and Robert, for their great work on this project and
ensuring that all of the material will help our readers realize the goal of developing mobile
applications on the new Windows Phone 7 platform.
—Nick
THANKS TO ALL AT WROX for their hard work in making my writing as good as it can be. In no par-
ticular order, thanks especially to Paul Reese for getting things off the ground, Ginny for infi nite
patience and good humour, and Kitty for her wordsmithing. Also, thanks to my fellow authors,
including many congratulations to Rob for getting through that “diffi cult fi rst book!”
—Karli
I COULD NEVER HAVE GOTTEN this far if not for my darling wife, Cara. You’re inspirational, patient,
and wonderful. Thank you for all the support you give me. Thanks to the staff at Wrox for all their
support and patience, especially Ginny and Paul. To all my mentors: Karli, Ben Gracewood, Dr. Rick
Mugridge, Dr. Ewan Tempero, David Okey, Alan Goodison, and especially my parents — thank you for
believing in me.
—Robert
