Visual Studio 2017 Error --Cannot connect to runtime process

Question

I am getting this error whenever I try to debug my project from visual studio.

I tried adding these settings to launchSettings.json but still no difference.

Answer 1

I had installed another file editor (Code Writer) that set itself as the default program for a whole host of files that were previously set to Visual Studio. Between a combination of doing a VS Installer Repair, and manually changing other associations back to VS, and a reboot, it's working for me again.
