  <p>I have absolutely no clue except that it seems like it can't find my assemblies. The code should be correctly compiled with public classes.</p>
  
  <p>Here is my .svc file:</p>
  
  <pre><code>&lt;%@ ServiceHost Language="C#" Debug="true" Service="QS.DialogManager.Communication.IISHost.RecipientService" CodeBehind="RecipientService.svc.cs" %&gt;
  </code></pre>
  
  <p>I have tried to create a very very simple service that contains just nothin too see if this would work but still the same old error shows up.</p>
