This method determines equality using the default comparer Comparer(Of T).Default. Comparer(Of T).Default checks whether type T implements System.IComparable(Of T) and uses that implementation, if available. If not, Comparer(Of T).Default checks whether type T implements System.IComparable. If type T does not implement either interface, this method uses Object.Equals.
This method is an O(n) operation, where n is Count.
