Remarks
The UserExtendedProperties API exposes two properties: ANID and ANID2.
ANID can only be accessed from Windows Phone OS 7.0 and Windows Phone OS 7.1 apps that use the Microsoft Advertising SDK for Windows Phone.
ANID2 can only be accessed from Windows Phone 8 apps.
The string returned by the ANID and ANID2 properties contains the anonymous identifier and is 32 characters long.
GetValue(String) provides the same functionality as TryGetValue(String, Object%), but uses a different syntax that you may prefer.
Capabilities
If you use this API in your app, you must specify the following capabilities in the app manifest. Otherwise, your app might not work correctly or it might exit unexpectedly.
