        manager.ArePreviewBuildsAllowed = true; 

        await manager.SyncAsync(); 

        PreviewBuildsState state = manager.GetCurrentState(); 
        string activationCode; 
        if (state.Properties.ContainsKey("ActivationCode")) 
        { 
            return state.Properties["ActivationCode"].ToString();
