title: How to call vb6 functions in c#
body: <p>How can I integrate some old VB6 functions/subroutines into a C# WebAPI project with least hassle? </p>
  
  <p>Is it really a manual rewrite? Or can I keep the old code and just call the functions from my C# code somehow?</p>
  
  <p>The code in question wasn't changed for the last six years and won't be changed for the next six years, but as everything goes web, it has to be reused in our Rest API.</p>
