Existing MVC Web Application with .NET standard library, IDE errors

Question

I converted one of our commonly used libraries to .NET standard 2.0 for mobile application use as well as use in existing applications.

Using this library in an existing Mvc application (4.7.1 Framework) it builds and runs successfully but the Visual Studio IDE reports a list of build errors for the controller classes around not being able to find elements of the library. The using clause of this library is also greyed out in the controller classes.

Is there an easy way to resolve this?
