Greetings, everyone. Charles Petzold’s free 24-chapter ebook, Programming Windows Phone 7, which you can find here, has been downloaded hundreds of thousands of times, which pleases us very much. We’re happy you find the work helpful, and we’re currently planning a second edition of the ebook (which will also be free). To help us provide an even better offering for “Mango,” we really need your feedback about the first edition of the ebook.
Please fill out our anonymous survey to give us feedback: http://www.microsoft.com/learning/booksurvey The survey will ask you for an ISBN to identify the title you’re commenting on. Enter this: 9780735643352
The survey is short and painless, we promise. And we do not ask for any personal information, nor will we contact you afterwards (because we don’t ask for any personal information).
