I'm not able to get my ANID?

Question

I have added to WMAppManifest.xml:

• <Capability Name="ID_CAP_IDENTITY_DEVICE" />
• <Capability Name="ID_CAP_IDENTITY_USER" />

So why do I keep getting empty strings from:

        public static string GetWindowsLiveAnonymousID()
        {
            int ANIDLength = 32;
            int ANIDOffset = 2;

            string result = string.Empty;
            object anid;
            if (UserExtendedProperties.TryGetValue("ANID", out anid))
            {
                if (anid != null && anid.ToString().Length >= (ANIDLength + ANIDOffset))
                {
                    result = anid.ToString().Substring(ANIDOffset, ANIDLength);
                }
            }

            return result;
        }

It does not seem to handle that TryGetValue very well... Someone got a clue?

Answer 1

It's called ANID2 in Windows Phone 8.

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.

Answer 2

use instead for Win Phone 8 apps

string anid = UserExtendedProperties.GetValue("ANID2") as string;

Also make sure those are checked from the WMAppManifest

<Capability Name="ID_CAP_IDENTITY_DEVICE" />
<Capability Name="ID_CAP_IDENTITY_USER" />
