Automation Test framework organization

Hi, I am working on Automation of some SFTP tasks with C#.
Do you know a proper way to organize classes as Test Cases, and then calling them from the Main method? to create a sort of Test Plan.
Because I see all examples for different operations are run from the Main method. That way I should create a different VS project for each Test Case.

Thanks!

I do not think you are asking on a correct forum.
