title: Nancy: Razor View Engine @using IntelliSense not working
body: <p>I have an IntelliSense problem with Nancy and the Razor View Engine.</p>
  
  <p>I try to use the functionality of an (self-made) external library inside my razor view. Therefore I reference the dll and try to put an @using and the namespace on top of the view to get some IntelliSense-Support.</p>
  
  <p>But it doesn't work. The @using can't find the dll or rather the namespace I have to put behind it. </p>
  
  <p>The VS-Error I get is: "The type or namespace name 'type/namespace' could not be found (are you missing a using directive or an assembly reference?)"  </p>
  
  <p>It just seems to be an IntelliSense problem because the engine is able to render the view if I use the correct @using on top of the view and ignore the error message or if I have a class inside my project which inherits from IRazorConfiguration and returns the needed namespace. </p>
  
  <p><strong>Notes:</strong></p>
  
  <ul>
  <li>Hosting: Self-Host and/or OWIN</li>
  <li>It works if the library is part of the same solution</li>
  <li>This happens with with Nancy 0.22.2 as well as 0.23 and the corresponding Razor packages.</li>
  </ul>
  
  <p><strong>Steps to reproduce (or better: things I did):</strong></p>
  
  <ul>
  <li>Create a new Console Application</li>
  <li>Install the Nancy Razor View Engine package</li>
  <li>Reference an external dll (namespace: External)</li>
  <li>Reference a dll which is part of the same solution (namespace: Same)</li>
  <li>Create a new Razor View</li>
  <li>Try: @using External -> not working</li>
  <li>Try: @using Same -> working</li>
  </ul>
  
  <p>I hope someone can help me even if It is not a <em>real</em> problem since razor is able to render the view but it's annoying :(</p>
