System.Configuration.dll fails to load when running a built project
How to reproduce:
1. Open the SampleScene in the attached "case_1183654-ioc" project
2. Enter play mode
3. Notice the working GUI Label
4. Build a project with "Development Build" setting enabled
5. Run the built project
Expected results: GUI Label is shown in both cases
Actual results: GUI Label is missing in a build, NullReferenceExceptions are spammed in the build log
Reproducible with: 2017.4.32f1, 2018.4.8f1, 2019.2.6f1, 2019.3.0b3, 2020.1.0a4
Additional notes:
1. Full error message:
UnloadTime: 1.562800 ms
FileNotFoundException: Could not load file or assembly 'System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its
dependencies.
2. It is possible that error "Loading assembly failed: "Assets/Plugins/System.Configuration.dll" will be thrown in the Editor Console Window, however, this error can be cleared, and it does not cause NullReferenceExceptions during play mode

Thank for answer.
Is it possible to bypass this limitation with something like [DllImport("my .NET System.dll")] ?
