56⟩ How to identify a device or a user?

Use Microsoft.Phone.Info.UserExtendedProperties.GetValue(“ANID”) in Microsoft.Phone.Info.dll. This is not in the MIX build. How unique is this Id? It identifies the user; so you could have a user with two phones. This is persisted across reboots, but not across factory reset (unless you reconfigure for same user).
