title: How to reference a namespace from a specific assembly?
body: <p>So here is my problem.</p>
  
  <ul>
  <li>My (test) project references both Castle Windsor and Rhino Mocks. </li>
  <li>I am creating a class which implements Castle.Core.Interceptor.IInterceptor from the Castle.Core.dll assembly</li>
  <li>In building Rhino Mocks, Ayende used Castle.Core.Interceptor and includes the whole darn namespace inside the Rhino.Mocks.dll</li>
  </ul>
  
  <p>So when I try to build, I get the error</p>
  
  <blockquote>
    <p>The type
    'Castle.Core.Interceptor.IInterceptor'
    exists in both
    'c:...\Libraries\Rhino.Mocks.dll' and
    'c:...\Libraries\Castle.Core.dll'</p>
  </blockquote>
  
  <p>How then do I specify that I want to use the IInterceptor instance from the Castle.Core.dll rather than the one included in Rhino Mocks?</p>
