title: Prism & MEF access to composed objects
body: <p>I am using Prism 4.0 with MEF. My application uses the [ImportingConstructor] attribute on its classes to construct objects. I need to gain access to the objects constructed. I believe Prism has a list of all the objects it created. Help me find the SomeObjectListSomewhere as shown below.</p>
  
  <p>Example:</p>
  
  <pre><code>public class Foo
  {
      private readonly INoob _noob;
  
      [ImportingConstructor]  
      public Foo(INoob noob)
      {
          _noob = noob
      }
  }
  
  public class NotNoob
  {
      public GoAction()
      {
          // I need Access to all INoob constructed objects here
          foreach (INoob noob in SomeObjectListSomewhere)
          {
               noob.DoSomething();
          }
      }
  }    
  </code></pre>
