How is MarshalByRefObject implemented?

Question

I would like to know how the MarshalByRefObject is implimented and why does it make it possible to pass objects by reference in remoting.

Is it possible because of the implementation of the MarshalByRefObject class, or does the remoting libraries just check whether the class derived from MarshalByRefObject?

Answer 1

The implementation of the MarshalByRefObject class itself is not that special; the important magic is implemented by the CLR (especially the JIT) at a low level. This has been discussed already as Jacob mentioned; some of the most useful information is in an article by 'cbrumme'.
