Ever thought developing applications for Windows Phone 7?
Well Microsoft is giving away a free book in PDF format (book is sold by Amazon at $25)
Regardless I’ve started playing around with the MS development environment for Windows Phone 7 and I like it a lot (I’ve even moved to a Windows Phone and can’t move back although it’s lacking many apps)

This book is a gift from the Windows Phone 7 team at Microsoft to the programming community, and I am proud to have been a part of it. Within the pages that follow, I show you the basics of writing applications for Windows Phone 7 using the C# programming language with the Silverlight and XNA 2D frameworks.
