Todd Baginski's Blog - A SharePoint, Mobile, Office, and Azure Blog
Over the winter, Matthew McDermott, Darrin Bishop and I spent a lot of time creating Windows Phone 7 applications that integrate with SharePoint sites. One of the things we figured out how to do is publish a SharePoint web site with a UAG Server to provide the ability to work with ASMX and REST based SharePoint APIs. Today the whitepaper which documents this process is available on MSDN.
You can download the Building Windows Phone 7 applications with SharePoint 2010 Products and Unified Access Gateway (UAG) (white paper) whitepaper here.
A special thanks goes out to Ben Ari for his help!
