title: The type was not found
body: <p>Visual Studio writes me some </p>
  
  <blockquote>
    <p>The type was not found. Verify that you are not missing an assembly
    reference and that all referenced assemblies have been errors in a WPF
    project from a  user control.</p>
  </blockquote>
  
  <p>When I press build the message dissapear and everything is ok. After a few seconds this message comes back and disturbs me.</p>
  
  <p>Why does the VS write this and how can I fix it? Thank you in anticipantion</p>
