title: Silverlight, reducing xap size setting, why dlls still included?
body: <p>I've used the "Reduce XAP size by using Application library caching" setting. I see that some dlls are now excluded from the .xap file but some aren't, specifically </p>
  
  <pre><code>System.Reactive.dll
  System.Windows.Controls.DataVisualization.Toolkit.dll
  System.Windows.Controls.Theming.Toolkit.dll
  System.Windows.Controls.Toolkit.dll
  </code></pre>
  
  <p>Any idea why this is the case?</p>
  
  <p>thanks</p>
