ROSLYN.USAGE.CA2231 : Overload operator equals on overriding value type Equals (C#)

See Roslyn-Detected C# Warning Classes for more information.

Summary

In most programming languages there is no default implementation of the equality operator (==) for value types. If your programming language supports operator overloads, you should consider implementing the equality operator. Its behavior should be identical to that of Equals.

This check corresponds to Roslyn rule CA2231. For full rule details, see the Microsoft website: CA2231.
