I have an nUnit 3.11.0 project that targets Core 2.1. I am running into an exception on one of my tests that says
Could not load file or assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.
The method works when running the application; it is the nUnit Core 2.1 that is not finding Linq. I tried to add a reference directly as a NuGet as per this post, but I can only find System.Linq (which didn't resolve the issue), and the post I was referencing seems to be a completely different issue.
