title: XamlParseException on setting image from resources
body: <p>i got some trouble. I just implemented the Microsoft Ribbon Framework into my application. Now i wanted to set an icon for one button. So i wrote:</p>
  
  <pre><code>    &lt;Ribbon:RibbonButton Header="Create Project" LargeImageSource="pack://application:,,,/Resources/document_empty.png" /&gt;
  </code></pre>
  
  <p>But everytime i start the app, i got an "XamlParseException" in this line, with the inner exception: "File not found".</p>
  
  <p>Why the hell is this so? I don´t understand, why it doesn´t find the image. It´s just placed in the resources of the assembly. The designer show´s it and the code doesn´t get highlighted as it was an syntax error or something like that...</p>
  
  <p>Anyone who has this problem too?</p>
  
  <p>Thanks!</p>
