[Mono-list] .NET Remoting Error on Mono

[Lluis Sanchez]

Hi,

What happened is that the database query that your remote method SayHelo
performs failed for some reason. You got an exception which Remoting
tried to send back to the client, but that exception object is not
serializable, and that is the error you are getting. Put a try/catch in
the server to see what's the database error.
