Windows Store Metro Apps: Is there a unique ID I can pull for a user?

Question

I've built some Windows Phone apps and one thing I like is the ability to pull a hash of the users LiveID from the phone so that users can be uniquely identified across devices.

Is there a good way to do this in metro apps. I'm sure I could use the device ID but then they're data wouldn't persist onto other devices they might own.

Anyone else have a good solution to this. I'm trying to avoid user registration in my app.

Thanks!

Answer 3

ApplicationData.Current.RoamingFolders or if just want to save a guid you can use roamingsettings

ApplicationData.Currnet.RoamingSettings.Value["USERID"]= Guid.NexGuid()
