title: Making actions get called in silverlight unit test with MOQ
body: <p>Lets say I have this</p>
  
  <pre><code>_articlesService.SaveAsync(Model, AddressOf OnSaveCompleted)
  </code></pre>
  
  <p>The OnSaveCompleteMethod do a couple of things, obviously. Its a </p>
  
  <pre><code>Protected Overridable Sub OnSaveCompleted(ByVal asyncValidationResult As AsyncValidationResult)
  </code></pre>
  
  <p>In my unittest. I need to run a mocked SaveAsync, and have OnSaveCompleted called in anyway, because the method sends out events that I need to know have been sent.</p>
  
  <p>Right now, the code just walks past that method, thus its never executed.</p>
  
  <p>Need help solving this because I'm stuck right now.</p>
