title: IronPython get to internal class from C# dll
body: <p>I'm using IronPython for fetching inner classes from C# dll.
  for example:  </p>
  
  <pre class="lang-cs prettyprint-override"><code>namespace Platform.CardHost {
      internal class ExtensionManager : IExtensionManager, IDisposable {
      //... other code
  </code></pre>
  
  <p>IronPython Code  </p>
  
  <pre class="lang-py prettyprint-override"><code>import clr
  clr.AddReference('Platform.CardHost')
  import Platform.CardHost.ExtensionManager
  # raise ImportError: No module named ExtensionManager
  # if it add to ref
  clr.AddReference('Platform.CardHost.ExtensionManager')
  # raise Error
  # IOError: System.IO.IOException: Could not add reference to assembly
  # Platform.CardHost.ExtensionManager
  </code></pre>
  
  <p>How can I import <code>ExtensionManager</code>? Or is this not possible?</p>
