First of all thank you very much for sharing this project.
I had a look at it and decided to try it but failed when built the applicaction. Let's see if you or someone could give a hand :).
I'm working with Codesys V3.5 SP14 patch 2 (64 bit) and CfUnit 0.0.2.1
I created an empty project with a Codesys Control Win V3 x64 device and added the library CfUnit and when built the project I got these errors (see image)
