What’s New in Windows Phone 7
WHAT’S IN THIS CHAPTER
An architectural overview of WP7
Comparisons with iOS and Android
Mobile application developers will fi nd it useful to have an architectural understanding of 
the underlying Windows Phone 7 (WP7) software platform. In particular, developers need 
to understand the application framework, its capabilities and limitations, and platform 
extensibility. It’s also important to know potential technical approaches to common 
development tasks. For Android or iPhone app developers, it’s vital to obtain a big picture 
of the new WP7 operating system.

Some terms can prove confusing because different people use them in different 
ways. For the purposes of this book, you’ll see iPhone Operating System (iOS) 
when the text discusses applications or code. The book uses iPhone when it asks 
you to perform an action with the physical device (or an emulator), such as 
clicking a button. In addition, we’ll use WP7 and Windows Phone 7 
interchangeably throughout the book.
The fi rst chapter of this book provides an overview of the new WP7 operating system, 
the history of Windows Mobile, the WP7 hardware platform (also known as the chassis 
specifi cation), the new Windows Compact Edition (CE) kernel, the application framework, 
the application store, and WP7 capabilities and limitations. Readers who aren’t familiar with 
Windows phone technologies will see examples that use Android or iPhone technologies. 
It’s important to understand the overall design philosophy of WP7 and its potential impact 
on the competition.
