I had the same issue error occur. I simply deleted the files found within the \IISExpress\config folder and reloaded the project by closing and opening Visual Studio.

This happens due to corrupt applicationHost.config file.

Instead of re-installing visual studio,

This should solve your problem.

I had the similar occurrence for a specific project only for VS 2015.

I went to the respective project folder .vs\config drive and deleted the applicationhost.config file. Then reloaded the project, and it created a new application host file and reloaded successfully.
