title: How to store a Collection of Objects in the Clipboard?
body: <p>I have a class <code>Slide</code>, of which I want to place several instances in the clipboard. It works perfectly fine for a single instance.<br>
  But when I try to, for example, put a  <code>List&lt;Slide&gt;</code> in the clipboard, the <code>SetDataObject</code> call will silently fail.<br>
  Internally, a COMException will be thrown and is swallowed. This is because <code>List</code> does not implement <code>ISerializeable</code>.<br>
  So, <code>List&lt;T&gt;</code> seems not to be an option. What would be the proper approach to place a collection of <code>Slide</code> instances in the clipboard?</p>
