If an ``++enum++`` member's name contains the word "reserved" it implies it is not currently used and will be change in the future. However changing an ``++enum++`` member is a breaking change and can create significant problems. There is no need to reserve an ``++enum++`` member since a new member can be added in the future, and such an addition will usually not be a breaking change. This rule raises an issue when the name of an enumeration member contains "reserved". == Noncompliant Code Example ---- using System; namespace MyLibrary { public enum Color { None, Red, Orange, Yellow, ReservedColor // Noncompliant } } ----
