title: which one to choose? DXCore, Resharper or VSX?
body: <p>I want to write a visual studio addon to do some code modifications for me (like some specific refactoring). I was wondering which one of these tools should I use and why?</p>
  
  <p>we have licenses for resharper, the other two are free and this is an internally used software, so we don't need to worry about licensing.</p>
