title: How do I attach commands to the checking and unchecking of a CheckBox?
body: <p>In my ViewModel I have two commands:</p>
  
  <pre><code>ICommand ExecuteMeOnCheck { get; }
  ICommand ExecuteMeOnUncheck { get; }
  </code></pre>
  
  <p>I wish to attach these commands to a CheckBox and have one of them execute when it is checked and the other execute when it is unchecked. What's the best way to achieve this without cluttering the View with code-behind?</p>
