title: Microsoft Unity: Interception not working when using BuildUp instead of Resolve
body: <p>I am using Microsoft Unity 2.0 and the interception extension is not working as expected.</p>
  
  <p>Consider these two lines of code:</p>
  
  <pre><code>MyUnityContainer.Configure&lt;Interception&gt;().SetDefaultInterceptorFor&lt;MyType&gt;(new VirtualMethodInterceptor());
  var someObject = MyUnityContainer.BuildUp&lt;MyType&gt;(anObject);
  </code></pre>
  
  <p>These two lines don't get you the dynamic proxy you'd expect for someObject! How can one make interception work for such a scenario?</p>
