Using Guantlet Automation Framework

We need to use Guantlet in a project.
We managed to have some batch scripts for stating a build, and running that build after many tries and checking the Automation c# project source.

However, we are still stuck. We found the ElementalDemo.cs example, but we don’t get where that sort of code should be placed in your project and how to make it run. Right now executing the test in a command line will say that the Test Name we introduce it’s not part of the Assemblies, which makes sense but… how to add it?

We are definitely lost in this, how to add that c# file to a project and compile it to an assembly?
How to add tests in c++?

Thanks
