title: How to find the C# component that contains a particular class
body: <p>I'm creating an Internet Explorer plugin using C#. I've been following a tutorial where the code imports a couple of classes that I don't have available, namely:</p>
  
  <pre><code>using System.Windows;
  using SHDocVw;
  </code></pre>
  
  <p>I realise I need to add the relevant components to my project but I'm not sure how to find the components that contain the classes. Perhaps there is a search somewhere?</p>
