D'Oh! Post a question that you've been puzzeling over for a while and take a break. Then of course the answer hits you and it's totaly obvious! I was forgetting to configure the MsmqTransport, my working code is below for anyone that's interested.
Configure config = Configure.With();
config
.CastleWindsorBuilder()
.XmlSerializer()
.MsmqSubscriptionStorage()
.MsmqTransport()
.IsTransactional(true)
.PurgeOnStartup(false)
.UnicastBus()
.ImpersonateSender(false);
config
.MsmqSubscriptionStorage()
.Configurer
.ConfigureComponent(NServiceBus.ObjectBuilder.ComponentCallModelEnum.None)
.ConfigureProperty(x => x.InputQueue, "testapps_messagebus")
.ConfigureProperty(x => x.NumberOfWorkerThreads, 1)
.ConfigureProperty(x => x.ErrorQueue, "testapps_errors")
.ConfigureProperty(x => x.MaxRetries, 5);
IBus bus = config
.CreateBus()
.Start();
bus.Publish(new Message(DateTime.Now));
