A little over a year ago I wrote a book: Microsoft SharePoint 2010 Enterprise Applications on Windows Phone 7 . Packt Publishing has since taken three of the chapters from this book and added them to a compendium: Microsoft SharePoint 2010 Developer’s Compendium: The Best of Packt for Extending SharePoint . And for a limited time you can purchase this book at a discount during Packt Microsoft Carnival .
See the site for more details, and let me know via Twitter @spatacoli if you want some help updating any of my examples for Windows Phone 7.5 since my book was written for Windows Phone 7.0 a lot has changed.
Also, I would like to write another book and give some talks. If anyone has suggestions or think this is a good idea, please let me know!
Thanks for your support.
