title: Implementing themes in Silverlight 4 apps
body: <p>I have a 2 part question:</p>
  
  <ol>
  <li><p>Is there anything more to implementing themes than simply placing a <code>&lt;toolkit:BlahBlahBlahTheme&gt;</code> tag around all your content?</p></li>
  <li><p>What is the pattern for switching out themes at runtime?  Is there such a thing?</p></li>
  </ol>
