Recently had this error popping up when I fiddled with the web.config.

Easiest solution was to get the latest MVC update VIA nuget, after first getting rid of the existing error references.

This page will show you what to type into your Nuget console in Visual Studio. (You can get other versions from here as well if you are not interested in the latest)

Good luck buddy.
