I use

Answer 1

This happened to me.

For me, the reason was a bad IIS config file.

I was able to fix it by deleting the auto-generated IISExpress folder, which is usually located at %userprofile%/Documents, e.g. C:\Users\[you]\Documents\IISExpress.

When I ran the project again, it created a new folder with a valid IIS config file and I could run the debugger.

Answer 2

This happened to me in a Web Site Project. The solution was to close the solution, delete the project's .vs folder and rebuild.
