title: Hangfire - new server appears every time code changed
body: <p>I'm new to Hangfire. I have it working on a dev machine but every time I change the code and run the app (asp.net Core 2 MVC) - a new server appears in the list on the dashboard.</p>
  
  <p>I can't find anything in the documentation about this - or in the sample files. I've read about cancellation tokens but these seem to be for intentional shutdown requests not code updates?!</p>
  
  <p>Is this expected behaviour? Am I expected to manually restart the application in IIS every time code is updated (more important on the server than dev machine obviously).</p>
  
  <p>Thanks.</p>
