[Mono-devel-list] Remoting Problem

[Lluis Sanchez]

Hi Willi,

The best way of reporting this kind of issues is to fill a bug report in
bugzilla.ximian.com, providing information about the mono version you
are using, and providing a simple test application we can use to
reproduce the problem.

Thanks!
Lluis.
