Hi there,
I get a

System.Runtime.Serialization.SerializationException
Because of security restrictions, the type
System.Runtime.Remoting.ObjRef cannot be accessed.

exception when I try to the object from the client to the
server.

I create my Client like this:

tcc = new TcpClientChannel();
ChannelServices.RegisterChannel(tcc);
remoteInterface = (IRemoteServer.RemoteInterface)
Activator.GetObject(typeof
(IRemoteServer.RemoteInterface), "tcp://localhost:8000/Rem
oteClass");

The server is created like this

hts = new TcpServerChannel(8000);
ChannelServices.RegisterChannel(hts);
RemotingConfiguration.RegisterWellKnownServiceType(typeof
(BankDetailsClassLibrary), "RemoteClass",
WellKnownObjectMode.Singleton);

It works until I try to pass the object from client to
server. Is there a workaround?

Thanks a lot

Chris
