Remarks

If the collection represented by the other parameter is a HashSet<(Of <(T>)>) collection with the same equality comparer as the current HashSet<(Of <(T>)>) object, this method is an O(n) operation. Otherwise, this method is an O(n + m) operation, where n is Count and m is the number of elements in other.
