Two objects are compared by Equals() but the comparison will always fail.
This checker identifies incorrect or inefficient comparisons through Equals() or ==. In some cases, these comparisons are wrong: for instance, strings should be compared for equality through Equals() rather than through ==. Classes can be safely compared through == instead. In other cases, these comparisons can be replaced by more efficient code.
