Teamcity System.IO.FileLoadException on UnitTests


In TeamCity my build configuration can restore and build my solution but when running tests it fails looking for Newtonsoft.Json version

I've turned logging onto diagnostic and can see that my redirects are working and version is being used when building each project.

This project has two test classes, only one is failing (all tests in this class are failing as the constructor call new MoqMockingKernel() which is the line in the stack trace below).

Happy to provide more information as needed. It's an MSBuild 15.0 configuration.

I've tried adding Newtonsoft.Json to the test project directly but am still getting the same error below. These tests have worked previously but I just cannot seem to figure out what change has caused these tests to break.

Here is the stack trace from the test:

System.IO.FileLoadException : Could not load file or assembly 'Newtonsoft.Json, Version=, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies.
