Just retested using the supplied test case and the error is still there when I
use revision 112336 of the svn repository.  (Server on Mono, Client on windows)

Did a little investigation as well and the error seems to come from the class
System.Runtime.Remoting.Channels.CrossAppDomainData where the _ContextID field
is of type System.Object in  mscorlib, Version= and in Mono the same
field is declared as an int  (with the comment: Never used but possible
required for .NET compatibility).

When I change field to an Object, the error is gone and the client is able to
pass an object reference to the server from windows to mono.
