title: Suppress/Stop/Get rid of Source Not Found tab in Visual Studio 2017
body: <p>I'm debugging an azure function written in core 2.0 (not sure if either of those datapoints are relevant but just in case).  </p>
  
  <p>When an error occurs at a line of "my"[1] source code, a new tab pops open with Source Not Found and then some diagnostic information not very clear to me you can see here [2].  Also, the pause button is no longer blue but grey. If I click on green continue button, the [grey] pause button goes blue again. But execution has left my function, no later break points have been hit, clearly the exception has been throw "into" the host / emulator / whatever. </p>
  
  <p>In a console app, when debugging and when an exception occurs, the execution pointer stops on the line of the exception and a dialog pops up explaining the exception.  I can then drag the execution pointer back up (and in good ol .net framework, even edit and continue!).</p>
  
  <p>What can I do to get the behaviour I'm currently experiencing to be a bit more like when I debug a .net framework console app?</p>
  
  <p>I get the feeling that I've provided only a very amateurish explanation of what 's happening, do feel free to comment I can rewrite if necessary.</p>
  
  <p>Cheers!</p>
