Hi i'm using mono on windows.

I have a remoting server and a client.

I run the server and the client, the client invokes two methods and
then try to invoke the third and then it gets an exception:

Unhandled Exception:
System.Runtime.Serialization.SerializationException: There are some
fixups that refer to objects that have not been registered

Server stack trace:

Exception rethrown at [0]:

in <0x006d1> System.Runtime.Remoting.Proxies.RealProxy:PrivateInvoke
System.Runtime.Remoting.Proxies.RealProxy rp, IMessage msg,
System.Exception exc, System.Object[] out_args)

If i run the client with .NET i got this other exeption:
Unhandled Exception: System.Net.WebException: The remote server
returned an error: (400) Bad Request.

Server stack trace:
   at System.Runtime.Remoting.Channels.Http.HttpClientTransportSink.ProcessResponseException(WebException
webException, HttpWebResponse& response)
   at System.Runtime.Remoting.Channels.Http.HttpClientTransportSink.ProcessMessage(IMessage
msg, ITransportHeaders requestHeaders, Stream requestStream,
ITransportHeaders& responseHeaders, Stream& responseStream)
   at System.Runtime.Remoting.Channels.SoapClientFormatterSink.SyncProcessMessage(IMessage

Exception rethrown at [0]:
   at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage
reqMsg, IMessage retMsg)
   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData&
msgData, Int32 type)
   at Common.IServicio.getPeticionesWeb(String Usuario, String Llave1,
String Modulo, String NReporte, String Fechas)
   at Cliente.Cliente.Main(String[] args)

The code should be fine because if the server is run with .net the
client works running on top of .net and mono

The code could be found here: http://monoport.com/296

I have the interface IServicio and the class User in a dll assembly
Common.dll, and the class Server on Server.exe wich starts the
remoting services and is compiled with Common.dll and Client on
Client.exe wich use the remoting servise and also is compiled with

What is the problem? is it a mono bug? if it is does exists a workaround?

Please note that the code is a simple test case that i got striping
the real code for testing.
