An error occurred attempting to determine the process id of the DNX process hosting your application

Question

I get this error message when I\'m trying to start the application.

An error occurred attempting to determine the process id of the DNX process host

Answer 1

I hit this problem due to the project config trying launch https://localhost instead of http. Right click on the webproject, under "Debug" and adjust "App URL" to be http instead of https.

Another way to get around this was switching the launcher from "IIS Express" to "Web"
