title: P/Invoke tutorials?
body: <p>Does anyone know of a good tutorial/e-book that goes in depth on the System.Runtime.InteropServices namespace? I just got through reading <a href="http://www.blackwasp.co.uk/ElevatedButton.aspx" rel="noreferrer">this</a> tutorial on how to make the UAC shield show up in a button and now I really want to learn this. </p>
  
  <p>P.S. How do look in the windows system files to know that a method exist to show a UAC shield in a button?</p>
