  1. POAzure AppFabric Service Bus Echo sample not working
    text
    copied!<p>I'm trying to run the Echo sample between two machines on my local network. The sample uses the netTcpRelayBinding and it works fine if I run both the service and the client on the same machine. When I first compiled the services and put it on my other machine, a Windows 2003 Server with no dev tools installed. It wouldn't run because it didn't know what netTcpRelayBinding was in the app.config. So I moved the config to code only and the service started. I confirmed this with the Service Bus Explorer. I then tried to connect with my dev machine (through VS2010) but it won't work. I have tried to change stuff both on the service and the client, trying all the combination of settings I can think of, but nothing. I mostly get one of two errors on the client: </p> <p>"ContractDescription 'IEchoContract' has zero operations; a contract must have at least one operation." </p> <p>or </p> <p>"there was no endpoint listening that could accept the message".</p> <p>This is the server code, my change is between the custom comments.</p> <pre><code>// create the service URI based on the service namespace Uri address = ServiceBusEnvironment.CreateServiceUri("sb", serviceNamespace, "EchoService"); // create the credentials object for the endpoint TransportClientEndpointBehavior sharedSecretServiceBusCredential = new TransportClientEndpointBehavior(); sharedSecretServiceBusCredential.CredentialType = TransportClientCredentialType.SharedSecret; sharedSecretServiceBusCredential.Credentials.SharedSecret.IssuerName = issuerName; sharedSecretServiceBusCredential.Credentials.SharedSecret.IssuerSecret = issuerSecret; // create the service host reading the configuration ServiceHost host = new ServiceHost(typeof(EchoService), address); // custom host.AddServiceEndpoint( typeof(IEchoContract), new NetTcpRelayBinding(), "EchoService" ); // custom end // create the ServiceRegistrySettings behavior for the endpoint IEndpointBehavior serviceRegistrySettings = new ServiceRegistrySettings(DiscoveryType.Public); // add the Service Bus credentials to all endpoints specified in configuration foreach (ServiceEndpoint endpoint in host.Description.Endpoints) { endpoint.Behaviors.Add(serviceRegistrySettings); endpoint.Behaviors.Add(sharedSecretServiceBusCredential); } // open the service host.Open(); </code></pre> <p>This is the client code, my current change is between the custom comments:</p> <pre><code>// create the service URI based on the service namespace Uri serviceUri = ServiceBusEnvironment.CreateServiceUri("sb", serviceNamespace, "EchoService"); // create the credentials object for the endpoint TransportClientEndpointBehavior sharedSecretServiceBusCredential = new TransportClientEndpointBehavior(); sharedSecretServiceBusCredential.CredentialType = TransportClientCredentialType.SharedSecret; sharedSecretServiceBusCredential.Credentials.SharedSecret.IssuerName = issuerName; sharedSecretServiceBusCredential.Credentials.SharedSecret.IssuerSecret = issuerSecret; // create the channel factory loading the configuration //ChannelFactory&lt;IEchoChannel&gt; channelFactory = new ChannelFactory&lt;IEchoChannel&gt;("RelayEndpoint", new EndpointAddress(serviceUri)); // custom ServiceEndpoint endpoint = new ServiceEndpoint(new ContractDescription("IEchoContract", "Microsoft.ServiceBus.Samples"), new NetTcpRelayBinding(EndToEndSecurityMode.Transport, RelayClientAuthenticationType.None), new EndpointAddress(serviceUri)); ChannelFactory&lt;IEchoChannel&gt; channelFactory = new ChannelFactory&lt;IEchoChannel&gt;(endpoint); // custom end // apply the Service Bus credentials channelFactory.Endpoint.Behaviors.Add(sharedSecretServiceBusCredential); // create and open the client channel IEchoChannel channel = channelFactory.CreateChannel(); channel.Open(); </code></pre> <p>My app.config files are cleared of the settings. I haven't touched any other files.</p>
