title: IE addon to inject java script
body: <p>I have successfully created extensions for chrome and Firefox that utilize content script to inject javascript.</p>
  
  <p>What is the best way to accomplish the same thing for an IE add on?
  The information I have found so far points to a bho written in c++ as .net has performance drawbacks.</p>
  
  <p>I have extensive knowledge of .net but new to c++.</p>
  
  <p>Any working example available with installer?</p>
