Should I provide a deep clone when implementing ICloneable?

Question

It is unclear to me from the MSDN documentation if I should provide a deep or a shallow clone when implementing ICloneable. What is the preferred option?

Answer 1

Short answer: Yes.

Long Answer: Don't use ICloneable. That is because .Clone isn't defined as being a shallow or a deep clone. You should implement your own IClone interface, and describe how the clone should work.
