private async void buttonSet_Click(object sender, RoutedEventArgs e)
{
      Uri nextImageUri;
      nextImageUri = new Uri("file:///" + Windows.ApplicationModel.Package.Current.InstalledLocation.Path + "/DefaultWallpaper.jpg", UriKind.RelativeOrAbsolute);

      try
      {
            bool isProvider = Windows.Phone.System.UserProfile.LockScreenWallpaperManager.IsProvidedByCurrentApplication;
            if (isProvider)
            {
                  Windows.Phone.System.UserProfile.LockScreenWallpaper.SetImageUri(nextImageUri);
            }
            else
            {
                  var op = await LockScreenWallpaperManager.RequestAccessAsync();
            }
      }
      catch (System.Exception ex)
