title: C# And windows explorer context menu?
body: <p>I have an idea for a little C# program, where I want to be able to right click on a file in windows explorer and somehow 'tag' that file.  Subsequent right clicks would show it's tagged state.  </p>
  
  <p>Bottom line is that I need to be able to right click on a file, see a custom menu item and perform a custom action as well as visualize some info.</p>
  
  <p>Never having done this, I'm not even sure where to start... :) </p>
  
  <p>Any good example out there?  Things I should read up on?  Links?</p>
  
  <p>Thanks!</p>
