.Net Remoting Question

Question

I have built a remote object which is held by IIS, and I have a client calling the remote object with parameter inherited from MarshalByRef. It work fine when I was using .Net Framework 1.0. However, I have upgraded the Machine to .Net Framework 1.1. I found that the remote object can no longer work wells. I realized that the .Net Framework 1.1 has changed the default deserialization level to Low. Later, I found that I someone said it can change the config file for setting the deserialization level to Full, which may works in my suitation. Then I have changed the Web.config to the following. ********** ********** and I have changed the client code in creating the remote object as follow, ********** SoapServerFormatterSinkProvider serverProv = new SoapServerFormatterSinkProvider(); serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full; SoapClientFormatterSinkProvider clientProv = new SoapClientFormatterSinkProvider(); System.Collections.IDictionary props = new System.Collections.Hashtable(); props["port"] = 0; HttpChannel httpChannel = new HttpChannel( props, clientProv, serverProv ); ChannelServices.RegisterChannel( httpChannel ); _interface = ( Interface ) Activator.GetObject( typeof( Interface ), "http://192.1.1.192/RemoteObject/RemoteObject.rem"); ********** It still throw the same exception with the following message, "Because of security restrictions, the type System.Runtime.Remoting.ObjRef cannot be accessed." However, if I try to host the Remote Object in a Console Program with the following code, ********** SoapServerFormatterSinkProvider serverProv = new SoapServerFormatterSinkProvider(); serverProv.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full; System.Collections.IDictionary props = new System.Collections.Hashtable(); props["port"] = 8080; HttpChannel httpChannel = new HttpChannel(props, null, serverProv); ChannelServices.RegisterChannel( httpChannel ); RemotingConfiguration.RegisterWellKnownServiceType( typeof( myObject.Remote ), "RemoteObject", WellKnownObjectMode.SingleCall ); ********** and the Client is the same except the url is, ********** "http://192.1.1.192:8080/RemoteObject" ********** Everythings work fine. Can anyone help me in this problem?
