From the author: When Microsoft announced that its new mobile platform, Windows Phone 7, would only be programmable with managed code, there was a loud applause (at least in the room I was in). Developers were keen to utilize their hard-earned knowledge of the .NET framework on the new platform and enjoy the ease of development and familiar tools and workflow on what is the most dynamically advancing area of computing - smartphones.
Microsoft brought two of its most interesting development frameworks to the phone: XNA and Silverlight. Silverlight developers can also right at home with Windows Phone 7. It is said that if you are already a Silverlight developer, you already know 90% of what is needed for developing Silverlight applications for the phone. This e-book is about the remaining 10%, written by Silverlight MVP and author of the WP7 app "SurfCube 3D Browser": András "@vbandi" Velvárt.
Note: this e-book covers Windows Phone 7.0 development. Footnotes have been added where Mango (the upcoming update of Windows Phone 7) is different, but the Mango API is not detailed here.
