According to the Microsoft Press blog, my book-in-progress Programming Windows Phone 7 Series now has a new title, Programming Windows Phone 7:
To celebrate VS Live (currently taking place without me in Redmond), Microsoft Press is releasing a second "draft preview" of the book containing several new chapters. All code has been updated for the public beta of the Windows Phone 7 Development Tools dated July 26 and available through the Windows Phone 7 developers portal.
I'll be updating my links to the book later today; meanwhile, you can download the new preview through links on the Microsoft Press blog entry.
The complete book will also be a free download, and will be unveiled in conjuction with this year's PDC in late October.
