title: "Operation could destabilize the runtime" Message when using RDLC
body: <p>When running an RDLC, I get the following message displayed inside the report frame:</p>
  
  <pre><code>Failed to load host assembly. Operation could destabilize the runtime.
  </code></pre>
  
  <p>Does anyone have any idea which assembly is being referred to. Better still, where is there a seam I can check to figure out which assemblies are being loaded and which are not. I don't think this is an issue with the RDLC assemblies themselves because: </p>
  
  <ol>
  <li>I've installed the report viewer locally.</li>
  <li>Other RDLC's work (or at least load).</li>
  </ol>
  
  <p>I'm truly baffled on this one. Many thanks for whatever help is offered.</p>
