This sample code will demonstrate how to call a Claims-Aware WCF Service from a SharePoint 2010 Claims Site. We use Service Application Framework (SAF) to host WCF Web Service in IIS. On the caller's side, we need to use CreateChannelActingAsLoggedOnUser method to send the Claim based SharePoint Logged-on user's security token to our custom web service. In our custom WCF web service, we need to use System.Threading.Thread.CurrentPrincipal.Identity to get the claim based security token.
