title: Cannot convert to same type in WCF
body: <p>I am building a test-stub for a webservice, implementing the interface retrieved from the production webservice using svcutil. When calling a method on the stub i get the exception;</p>
  
  <pre><code>Object of type 
  'Sbsys.Services.HostService.DokumentBoks.DKALWSAfsendService.MaterialeType[]' 
  cannot be converted to type
  'Sbsys.Services.HostService.DokumentBoks.DKALWSAfsendService.MaterialeType[]'.
  </code></pre>
  
  <p>where 'Sbsys.Services.HostService.DokumentBoks' is the namespace of the consuming client, and 'DKALWSAfsendService' is the namespace containing the generated proxy classes for the service.</p>
  
  <p>Any ideas on whats going on?</p>
  
  <p>Bonus info: When using the production service everything works as intended</p>
