title: MahApps.Metro cannot find resources
body: <p>I am trying to create new WPF application usign MahApps.Metro. I do exactly as described in quick start guide (<a href="http://mahapps.com/MahApps.Metro/guides/quick-start.html" rel="noreferrer">http://mahapps.com/MahApps.Metro/guides/quick-start.html</a>):</p>
  
  <ul>
  <li>Add MahApps.Metro package from Nuget to the project.</li>
  <li>Add xmlns namespace and replaced Window with MetroWindow.</li>
  </ul>
  
  <p>At this point I can run the application, but the window is transparent. Title bar text and buttons are visible (and buttons are not styled), but the background is transparent.</p>
  
  <ul>
  <li>Add merged dictionaries code for the Window.</li>
  </ul>
  
  <p>After that I receive an exception on startup:</p>
  
  <pre><code>System.IOException
  {"Cannot locate resource 'styles/colours.xaml'."}
  </code></pre>
  
  <p>Seems as for some reason it cannot find resources in the assembly. But I don't understand why.</p>
