Question

When we used AppDomain.CreateInstance(‘Assembly name’, Type name) and my class inherits from MarshalByRefObject what happen internally? Is it create a TransparetnProxy?

Code:

class Greet : MarshalByRefObejct {   ... }  class test {  public static void Main(string[] args)  {    AppDomain ad = AppDomain.CreateDomain('Second');    ObjectHandle hObj = ad.CreateInstance('Test', args[0]);   ....  } } 

passing in args[0] = Greet

Answer 1

Yes, it creates a transparent proxy, which you get by unwrapping the object handle.

I find the documentation and example for ObjectHandle.Unwrap is quite informative, as is the general MarshalByRefObject documentation.
