Overload operators the right way in C#

It’s a good rule of thumb to overload the equality operators on classes. That ensures a correct comparison between to class instances of the same type. If you don’t, .NET automatically uses reflection and that is way slower than a custom implementation. We all use the equality operators (“==”, “!=”) all the time and we expect them to be right every time. They are not!, but even if they were there is a good chance that you want to change them anyway.
