Is there any way to look up liveID related to a phone (in a way like myliveid@hotmail.co.uk)? I think it was possible in Android. Wouldn't UserExtendedProperties.TryGetValue("ANID") be helpful? Thanks
If you run UserExtendedProperties.TryGetValue("ANID") you'll get a GUID (the windows live anonymous id), but you can't use that GUID to link it to an Live ID like myliveid@hotmail.co.uk
