Why does Visual Studio by default create a private static method when refactoring code and selecting extract method?
If I'm refactoring a non-static class and the method is only visible within the class why is it static?
Is there some performance benefit by calling a private static method within a non-static class compared to a non-static method within a non-static class?
Is it for readability to simply show that the method does not rely on any member variables of the class?
