Last week during a training one of the participants got the following error when she tried to debug a web application in IIS Express. IIS Express failed to start and Visual Studio showed the following error message:
Process with an ID #### is not running
We couldn’t find the root cause of the issue but we had a workaround to fix it:
- Close Visual Studio.
- Delete the hidden
.vsfolder on solution level
- Open your solution again
- This time IIS express should be back up and running
