Things that transport used to require that are passed via settings, not via seam:
Settings.Set("Endpoint.SendOnly", sendOnly);
Settings.Set("TypesToScan", new Type[0]);
Settings.Set("NServiceBus.Routing.EndpointName", endpointName);
Settings.Set<Conventions>(new Conventions()); //Hack for ASB
Settings.Set(new StartupDiagnosticEntries());
