WCF会话 - Servic Fabric状态服务

Question

基于https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-services-communication-wcf

提供的文档

WCF中的有状态服务是否支持会话？

尝试了以下属性，但它不起作用。

[ServiceBehavior（InstanceContextMode = InstanceContextMode.PerSession）]

公共类CalculatorService：ICalculator

[的ServiceContract（SessionMode = SessionMode.Required）]

public interface ICalculator

我需要做哪些更改WCFCommunicationListener来支持会话？

Uri resourceAddress;
        if (!Helpers.TryGetUri(pcHost + pcPort + "/api/code/scan", out resourceAddress))
        {
            rootPage.NotifyUser("Invalid URI.", NotifyType.ErrorMessage);
            return;
        }
        try
        {
            terminalRef = "1";
            //code = "Uc0E17G4nW";
            IHttpContent jsonContent = new HttpJsonContent(JsonValue.Parse("{\"code\":\"" + code +
                                                                            ",\"ref\" : \""+ terminalRef +
                                                                            "\"}"));





            HttpResponseMessage response = await httpClient.PostAsync(resourceAddress, jsonContent).AsTask(cts.Token);
            Debug.WriteLine(".");
            //await Helpers.DisplayTextResultAsync(response, cts.Token);
            rootPage.NotifyUser("Completed", NotifyType.StatusMessage);


        }
        catch (Exception ex)
        {
            rootPage.NotifyUser("Error: " + ex.Message, NotifyType.ErrorMessage);
            String errorMessage = ex.Message.ToString();
        }

我可以使用以下代码在WCF状态服务中实现会话。

protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
    {
        return new[]
        {
            new ServiceReplicaListener( (context) =>
             {
                var wcfCommunicationListener = new WcfCommunicationListener<ICalculator>(context, new CalculatorService(),WcfUtility.CreateTcpListenerBinding(),"WCFServiceEndpoint");                                        
                wcfCommunicationListener.ServiceHost.Description.Behaviors.Remove(typeof(ServiceBehaviorAttribute));
                wcfCommunicationListener.ServiceHost.Description.Behaviors.Add(new ServiceBehaviorAttribute() { InstanceContextMode = InstanceContextMode.PerSession});                    
                return wcfCommunicationListener;
             }   
            )
       }; 
    }
