For a class to be cloneable it must implement the interface ICloneable and the method 'public object Clone()', just like Java. However, unlike Java, Object does not implement a shallow clone method. This means that the logic you implement in your own clone method cannot call the super (or base as it is in C#) class's Clone method to get a typed, shallow clone. This would not necessarily be a big deal as you could just create a new class that you are attempting to clone, but if you do this you would have to be able to clone its properties (assuming they are publicly accessible or can be set via a constructor) manually -- a cumbersome task.
