How to make a hidden method visible to another assembly in C#?

Question

C++ / C#

I want to create a unit test for the method, so I need to make it open for the project with tests. But at the same time, I would like to leave it hidden for the rest. Is there a way to do this? I suspect there must be some attributes.

Answer 1

As an option, you can try to make an overloaded public method with directives

#if(DEBUG)
public string GetMyAwesomeString(string anotherOne){
    return _getMyAwesomeString(anotherOne);
}
#endif

Accordingly, it will no longer be in the release.
