title: How to display app's form to display at desired monitor when debugging?
body: <p>When I press <kbd>F5</kbd> to debug my C# Windows form app, built with Visual Studio 2017 pro on Windows 10, the app window always displays on my main monitor, which is the middle monitor of my 3 monitors.</p>
  
  <p>Is there a 'trick' to always open and display on the left-hand monitor?
  (I want to use middle monitor to see the source code.)</p>
  
  <p>If no trick, then I must program form's x,y to persist across debug sessions.</p>
