A couple of weeks ago, I got the opportunity to meet and chat with several XNA and DirectX MVPs at the 2011 MVP Summit on the main Microsoft campus in Redmond, Washington. At the summit, a couple of the MVPs, Chris Williams and George Clingerman, were autographing copies of their new book, Professional Windows Phone 7 Game Development – Creating Games Using XNA Game Studio 4.
The book was released in February 2011, and it provides in-depth information about developing and publishing Windows Phone 7 games using XNA Game Studio 4.0, including 3 complete games. If you are looking into developing games using XNA Game Studio and the Windows Phone 7 platform, I encourage you to check out this book. You can find it on Amazon.com and at other retailers.
