title: How to increase the size of a SymbolIcon in XAML?
body: <p>I have a button that I want to use to launch video playback, so it should look like a "Play" button. The button will be fairly large on screen. This is what I have so far:</p>
  
  <pre><code>&lt;Button Style="{StaticResource PlayButton}"&gt;
      &lt;SymbolIcon Symbol="Play"/&gt;                                
  &lt;/Button&gt;
  </code></pre>
  
  <p>The PlayButton resource defines a MinHeight and MinWidth of 200px. The problem with this is that the play icon is very small, in the order of 16px or so. How can I make it larger?     I tried setting FontSize="200" in the Button declaration, but it makes no difference.</p>
