About the Authors

■ Henry Lee is the founder of NewAgeSolution.net and is passionate about
technology. He works with various Fortune 500 companies, delivering mobile
applications and rich Internet applications. He recently formed a startup company
called ToeTapz.com, focusing his energy on delivering mobile applications in
Windows Phone 7, Android, and iPhone. In his spare time, he dedicates his effort to
help his .NET community by delivering sessions at technology events. He enjoys
talking with other technologists about current trends in technology and sharing
business insights with fellow colleagues. Often you will find Henry at a local cigar bar,
enjoying a cigar and a drink, trying to come up with the next big mobile application.

■ Eugene Chuvyrov is an independent .NET consultant in beautiful Jacksonville,
Florida. He was lucky enough to start working with Microsoft technologies when he
graduated from college in 1998, and has been consistently delivering a positive return
on investment to the clients that engage him. His most recent venture is an online
event marketing startup, packedhouseevents.com, which extends event creation,
marketing, and electronic payments to anybody with Internet access. Eugene also
facilitates the meetings of the Jacksonville Software Architecture Group, where he
enjoys networking and learning from smart people.
As soon as Eugene heard the news that a new mobile platform (Windows Phone
7) was being released by Microsoft, he was immediately intrigued. It was hard to resist
the temptation of wide-open possibilities to create smartphone applications using his favorite IDE and
all the latest cloud and functional programming–based technologies. This passion, combined with a

unique opportunity to share our knowledge. Thank you, Ewan, for believing in us. Stefan Turalski has
given us consistent in-depth technical guidance and commentary—thank you for ensuring that we use
industry best practices at all times. John Osborn made our book understandable not only to the two of
us, but to the rest of the world as well. Thank you, John; we are much better writers now because of you!
Mary Ann Fugate performed very timely copyedit checks and ensured that all the references and
grammar made sense—thank you, Mary Ann.
However, this book would have never come to fruition if it weren’t for our coordinating editor,
Jennifer Blackwell. Jennifer encouraged us when we needed encouragement, provided guidance when
we were lost, and made us see the light at the end of the tunnel at all times. For that, we are extremely
grateful!

Introduction
We decided that we should write a book about something we enjoy doing to share with our fellow
developers to fulfill their dreams. This is how our journey started. When the startup company
NewAgeSolution.net was founded, the company emphasized delivering compelling rich Internet
applications using Silverlight. The company enjoyed great success, with eight employees, delivering
amazing Silverlight applications that you can read about in a Microsoft case study
(www.microsoft.com/casestudies/Case_Study_Detail.aspx?CaseStudyID=4000006798).
Then Microsoft invited many of the Silverlight partners to join the Windows Phone Partner
program, and after attending the Windows Phone partner conference in Redmond at the Microsoft
campus, we truly believed that the age of the smartphone had begun. It was a natural progression for us
to tackle Windows Phone, since Silverlight is one of the primary development platforms, and we were
able to utilize all the knowledge that we had gained over the years.
Windows Phone is our passion and our daily life, The Windows Phone market is big, and we want to
share our dream with you by showing you how to successfully develop a Windows Phone application so
you can also deploy your dream to the Marketplace.
Who This Book Is For
This book assumes that you have basic C# and .NET knowledge. This book will provide you with basic
fundamentals and skills that you will need to be successful in developing a Windows Phone application.

section concludes with step-by-step instruction on how to gain certification from Microsoft and offer an
application to the public through the Windows Phone Marketplace.
In Part 2, you will learn how to use specific features of Windows Phone devices in your applications,
including the accelerometer, location service, application bar, reactive extensions, application hub
integration, application life cycle events, isolated storage, Silverlight, XAML, skinning controls, web
browser controls, media elements, photos, push notifications, internalization, and security. While each
of its chapters is a tutorial, you can also use Part 2 as a reference. Each chapter will focus on a single
phone feature and provide step-by-step instructions on how to incorporate it into your application.

untapped as the market will open to the public on November of 2010, and you will have a chance to
publish an application that is first to the market. You might consider downloading Zune software from
www.zune.net/en-US/products/software/download/downloadsoftware.htm to view the current
Marketplace. Once you have downloaded the Zune software and fired it up, click marketplace ➤ APPS
links, and you will be able to see all the Windows Phone applications currently published, as shown in
Figure 1–1. You will learn more about the Marketplace in Chapter 5.
