WCF 会话 - 服务结构状态服务

Question

根据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

[ServiceContract(SessionMode=SessionMode.Required)]

公共接口ICalculator

---

我需要对 WCFCommunicationListener 进行任何更改以支持会话吗？

protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
    {
        return new[]
        {
            new ServiceReplicaListener( (context) =>
                new WcfCommunicationListener<ICalculator>(context, new CalculatorService(),WcfUtility.CreateTcpListenerBinding(),"WCFServiceEndpoint")
            )
       }; 
    }

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;
             }   
            )
       }; 
    }
