S1939 — Inheritance list should not be redundant

Why is this an issue?

An inheritance list entry is redundant if:

• It is Object - all classes extend Object implicitly.
• It is int for an enum
• It is a base class of another listed inheritance.

Such redundant declarations should be removed because they needlessly clutter the code and can be confusing.

Noncompliant code example

public class MyClass : Object  // Noncompliant

enum MyEnum : int  // Noncompliant

Compliant solution

public class MyClass

enum MyEnum
