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
Assuming you are running IIS Express with SSL Enabled depending on your installation you will have to put your IIS Express Development Certificate(Issued To "localhost"/ Issued By "localhost") in either [Local Computer\Personal\Certificates] or [Local Computer\Trusted Root Certification\Certificates]. One of those should work. (Using Windows 10 + VS2015). HTH
