title: Should I use MVVM or just a ContentControl for loading Screens?
body: <p>I am developing an Application with the following layout, 
  I have no knowledge of MVVM and I'm on a tight timeline.
  The Red area on the right is a ContentControl.
  The area on the left will be a sidebar for Navigation</p>
  
  <p><img src="https://i.stack.imgur.com/JG2To.png" alt="enter image description here"></p>
  
  <p>My question is </p>
  
  <ol>
  <li>should I follow this aproach
  <a href="http://channs.blogspot.com/2010/09/wpf-navigation.html" rel="nofollow noreferrer">http://channs.blogspot.com/2010/09/wpf-navigation.html</a> OR</li>
  <li>should I use MVVM light / Prism  OR</li>
  <li>should I use WPF pages?</li>
  </ol>
  
  <p>I am currently inclined to option 1. Are there any pros and cons to it?
  Which option would you recommend ?
  My application will always have only one developer i.e.  Me and it will contain about 30 screens.</p>
