[Mono-devel-list] RE: [Remoting-corba-developer] Remoting.Corba on Mono

[Kristopher Johnson]

Regarding the client-side error, it appears that either (a) an
IiopClientChannel or IiopChannel has not been registered, (b) the Mono
remoting infrastructure is not calling CreateMessageSink for the
registered channel, or (c) for some unknown reason,
IiopClientChannel::CreateMessageSink or IiopChannelBase::Parse doesn't
work right under Mono.

Regarding the server-side error, this appears similar to other errors
that have been reported using R.C with Mono.  Serialization of an IOR
just doesn't seem to work the same way with Mono. 

I don't have Mono installed, so I can't really check into this myself
right now.  A couple of people on the remoting-corba-developer list
are playing with Mono, so maybe they can investigate.
