Unable to run a class library project

I cloned a class library project from GitHub, I opened the solution with Rider, tried to run it, but couldn't figure out what was missing. I spent about two hours reading documentation and googling, but I was still stuck.

I opened the same solution with Visual Studio and ran it, and Visual Studio asked me to set the .exe file.

I picked the .exe file and ran it again, and it worked.

I went back to Rider, and I'm still unable to run it.

I don't know what details I should add to help you help me, well, if I knew it I could find the solution to the problem by myself. So I guess my first question is where do I start investigating?

This is what I see in the run configurations:
