Answer 2

According to the chart on this page: https://learn.microsoft.com/en-us/dotnet/articles/standard/library you need to upgrade your libraries to at least version 4.5 of the Framework.

I'm currently using version 4.6 of the Framework for my libraries and referencing them from an Asp.Net Core MVC Web Project without issue.
