[Mono-devel-list] can't AppDomain under the mint

[Хорольский Андрей Николаевич]

when I run below program under the mint(0.24&snapshort-18-May) I've got
exception:

Unhandled Exception: System.InvalidCastException: Cannot cast from source

public class X : MarshalByRefObject {

      public void Run ()
      {
        Console.WriteLine ("inside X; current domain: {0}",
AppDomain.CurrentDomain);
        AppDomainSetup ads = new AppDomainSetup ();
      }
    }

    public class R {
      public static void Main ()
      {
        AppDomain domain = AppDomain.CreateDomain ("X");
        Type t = typeof(X);
        X x = (X) domain.CreateInstanceAndUnwrap (t.Assembly.FullName,
t.FullName);
        x.Run ();
      }
    }

I've no such problems with mono/oldmono. Any suggestions would be greatly
appreciated.
