When I debug my solution, vs 2017 is very laggy and slow it\'s like it has to operate something heavy in the background.
So it stops \"responding\" every 5 seconds for 2
Only one thing that helped me was disabling Debugger option of Resharper. If you use Resharper, try to UNCHECK "Show local variables values in editor" in menu: Resharper -> Options -> Tools -> Debugger.
It helped for me.
