Hi Dino,

If have tweaked your code to reproduce the exception that I am facing. Let
me know if you need more details.

thanks,
Mustaq

using System;
using Microsoft.Scripting;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;

class Foo
{
    public static void Main(string[] args)
    {
        AppDomain ad = AppDomain.CreateDomain("foo");
        var engine = Python.CreateEngine(ad);
        engine.Runtime.LoadAssembly(typeof(MbrBase).Assembly);

        var code = engine.CreateScriptSourceFromString(@"
import MbrBase
class C(MbrBase):
    pass

a = C()
", SourceCodeKind.Statements);

        var scope = engine.CreateScope();
        code.Execute(scope);

        Console.WriteLine("Trying to do it... {0}",
AppDomain.CurrentDomain.Id);
        MbrBase mbr = (MbrBase)scope.GetVariable("a");

//     MY CHANGES

        string isSubClassCode = String.Format("issubclass({0},{1})", "C",
"MbrBase");
        ScriptSource script =
engine.CreateScriptSourceFromString(isSubClassCode,
SourceCodeKind.Expression);
        bool result = (bool)script.Execute(scope);

        if (result == true)
        {
            ObjectOperations ops = engine.Operations;

            object subClass = scope.GetVariable("C");
            object instance = ops.Call(subClass);

            mbr = instance as MbrBase;
        }

//      END OF MY CHANGE

        mbr.DoItVirtually();
        mbr.DoIt();
        Console.ReadKey();
    }
}

public class MbrBase : MarshalByRefObject
{
    public virtual void DoItVirtually()
    {
        Console.WriteLine("Did it virtually {0}", AppDomain.CurrentDomain.Id
);
    }

    public void DoIt()
    {
        Console.WriteLine("Did it {0}", AppDomain.CurrentDomain.Id);
    }
}
