So I managed to resolve this in my project. The issue is that the newest version of the lib AspNetCore.Razore.Language does not have the templating class. If any project in your solution uses the newer version of this dll the old version will not be copied into the output directory. You need to search through all your packages and make sure that razor version 2.2 is the newest one installed everywhere. If other parts of your project/solution require a newer version than 2.2 then you will not be able to use RazorEngine and will have to try one of the alternatives.

I fixed it by uninstalling Microsoft.VisualStudio.Web.CodeGeneration.Design (suggested by someone else) Uninstall-Package Microsoft.VisualStudio.Web.CodeGeneration.Design
