For those of you who attended my SPC 351 session at SharePoint Conference today (Hitting the Ground Running with Claims Authentication), there was a request for some source code. As promised, I'm attaching a zip file with the source to the Facebook DataView WebPart I demonstrated. It's based on using ACS to log into a SharePoint site with Facebook authentication, and then using the Facebook Access Token (that comes in a special SAML claim) to make a request out to Facebook for the user's public profile info. The source code is attached for your use and enjoyment. Hopefully the recorded SPC sessions will be posted somewhere; if not and there is sufficient demand (by my random estimate of your interest based on comments to this post) I may try and find a place to post a separate recording I did of the demo...my backup in case of network connectivity issues.
