Im using the Microsoft.Bcl.Async NuGet package. working on VS 2012 Pro.

The progress bar is not displayed even after making NewProgressBar Visible.

 private async void Button_Click(object sender, RoutedEventArgs e)
 {
      NewProgressBar.Visibility = Visibility.Visible;
      CloudResponse res = await WebService.Instance.MailMessage();
      NewProgressBar.Visibility = Visibility.Collapsed;

      if (res.success == 1)
           MessageBox.Show("Message sent succesfully");
      else if (!res.errorMessage.IsEmpty())
           MessageBox.Show(res.errorMessage);
 }
