[Mono-dev] Mono Webservices Bug

[Yngve Zackrisson]

Hi

I do not know if you have any help by this knowledge but 
I run .NET Remoting between a Win32 MS .NET client 
and a Linux (Fedora Core 3) Mono server.
I invoke the remote objects methods with HTTP (Binary Formater) 
and is able to both add DataSets as parameters and returns.

In other words, your problems seems to be specific to Webservices 
(in Mono).

Regards 

Yngve Zackrsson.
