Indeed, it does forward the calls, even if the methods are
not overloaded.
Here is what MS does:
http://msdn2.microsoft.com/en-us/library/h8f0y3fc.aspx
This timing test case reveals the forwarding:
using System;
using System.Reflection;
class Server : MarshalByRefObject
{
static void Main ()
{
AppDomain ad = AppDomain.CreateDomain ("foo");
Server s = (Server) ad.CreateInstanceAndUnwrap
(Assembly.GetExecutingAssembly ().FullName, typeof (Server).FullName);
TimeIt (new object ()); // lasts almost nothing
TimeIt (s); // lasts a couple of secs
}
static void TimeIt (object o)
{
DateTime b = DateTime.Now;
for (int i = 0; i < 100000; i++)
o.Equals (null);
Console.WriteLine (DateTime.Now - b);
}
}
Please file a bug.
Robert
