UserExtendedProperties requires the user identity capability. If your application uses this class, the user will be alerted that the application requires access to the value associated with the user’s identity when viewing your application on Windows Phone Marketplace. For this reason, we recommend that you use this class only if your application requires it. |
The string returned when querying for the anonymous ID by specifying the “ANID” property name contains the 32-character anonymous identifier as well as other information used by the system. To extract only the anonymous identifier, use the following code.
string anid = UserExtendedProperties.GetValue("ANID") as string;
string anonymousUserId = anid.Substring(2, 32);
