[Mono-list] .NET workaround for blank Action "" in SOAP message not handled in Mon

I've been troubleshooting an issue while trying to get a gSoap client to
communicate with a C# server using ServiceHost. When I first tried to get
the communication to work with a .NET server I ran across a problem where
the c# server was complaining about a mismatch in the SOAP Action field:

"The message with Action '' cannot be processed at the receiver, due to a
ContractFilter mismatch at the EndpointDispatcher. This may be because of
either a contract mismatch (mismatched Actions between sender and receiver)
or a binding/security mismatch between the sender and the receiver.  Check
that sender and receiver have the same contract and the same binding
(including security requirements, e.g. Message, Transport, None)."

I found a work around that causes the service host to do dispatch based off
of message body and not SOAP action. MSDN sample here:

referred by this forum post (which has little more detail on how to mod a
generated *.cs file):

This got my .NET/C# server working. However, the mono/C# server (same exact
code) still had a problem and it looks to be because of the blank SOAP
action field.

Anyone have any ideas?
