        Why is this an issue?

        How can I fix it?

        More Info

        When a class has only a private constructor, it can’t be instantiated except within the class itself. Such classes can be considered dead code and should be fixed

        Exceptions

        • Classes that access their private constructors (singletons or smart enums) are ignored.
        • Classes with only static members are also ignored because they are covered by Rule S1118.
        • Classes that derive from SafeHandle since they can be instantiate through P/Invoke.
