What does it mean exactly that only one instance of a static cass can exist in a program?

As far as I know you can not create an instance of a static class. Static classes do not contain any instance member properties or functions. So to make an instance would be pointless.

Essentially a static class is a class you cannot instantiate, meaning you cannot use the 'new' keyword to create it. An example of a static class is the System.Math class int result = Math.Min(10, 5); A class like this is typically referred to as a Utility class.
