title: How to set the background using acrylic brush through C# in UWP?
body: <p>I've tried the following:</p>
  <pre><code>{
      ContentDialog dialog = new ContentDialog()
      {
          Title = title,
          Content = text,
          CloseButtonText = closeButtonText
      };
      
      dialog.Background = new AcrylicBrush()
      {
          BackgroundSource = 0,
          TintOpacity = 0.5,
          Opacity = 0.5,  
      };
      
      await dialog.ShowAsync();
  }
  </code></pre>
  <p>P.S. - Sorry for the Russian and my bad English. Thank you in advance </p>
