Here is an elaboration of the answer by @schoetbi. You need to tell the class how to clone itself. C# does not distinguish between aggregation and composition and uses object references for both.

If you had a class for storing information about a car, it could have instances fields, like engine, wheels, etc. (composition), but also manufacturer (aggregation). Both are stored as references.

If you cloned the car, you would expect the engine and wheels to be cloned as well, but you certainly would not want the manufacturer to be cloned as well.
