    copied!<p>I have regular net.tcp WCF service client, and regular net.tcp <strong>duplex</strong> (i.e. with a callback) WCF service client. I have implemented some logic to constantly reinstantiate the connection in case a service has faulted.</p> <p>They are created in the exactly same way:</p> <pre><code>FooServiceClient Create() { var client = new FooServiceClient(ChannelBinding); client.Faulted += this.FaultedHandler; client.Ping(); // An empty service function to make sure connection is OK return client; } BarServiceClient Create() { var duplexClient = new BarServiceClient(new InstanceContext(this.barServiceCallback)); duplexClient.Faulted += this.FaultedHandler; duplexClient.Ping(); // An empty service function to make sure connection is OK return duplexClient; } public class Watcher { public Watcher() { this.CommunicationObject = this.Create(); } ICommunicationObject CommunicationObject { get; private set; } void FaultedHandler(object sender, EventArgs ea) { this.CommunicationObject.Abort(); this.CommunicationObject.Faulted -= this.FaultedHandler; this.CommunicationObject = this.Create(); } } </code></pre> <p>The <code>FaultedHandler()</code> aborts the channel and <strong>recreates</strong> it using the code above.</p> <p>The <code>FooServiceClient</code> reconnection logic works just fine, it is being reconnected after many faults. Whereas, almost the same but duplex <code>BarServiceClient</code> receives Faulted event only from the first <code>BarServiceClient</code> instance, i.e <strong>once</strong>.</p> <p>Why only the firsts instance of duplex <code>BarServiceClient</code> gets faulted event? Are there any workarounds?</p> <hr> <p>A similar non answered question: <a href="https://stackoverflow.com/questions/4703732/wcf-reliable-session-without-transport-security-will-not-faulted-event-on-time">WCF Reliable session without transport security will not faulted event on time</a></p>
