使用XAMLX服务

Question

当我目前使用BehaviorExtensionElement加载在ApplyDispatchBehavior方法被设立为ServiceBehavior如何挂钩WF4 WorkflowRuntime的事件：

事件

public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase) 
    { 
     WorkflowServiceHost host = serviceHostBase as WorkflowServiceHost; 
     if (host != null) 
     { 
      UnityService.CreateContainer(); 
      host.WorkflowExtensions.Add<IUnityContainer>(delegate { return UnityService.CreateChildContainer(); }); 

      System.Diagnostics.Debug.WriteLine("NotificationService : Adding extension"); 

      WorkflowRuntimeBehavior wfbehavior = serviceDescription.Behaviors.Find<WorkflowRuntimeBehavior>(); 
      WorkflowRuntime runtime = wfbehavior.WorkflowRuntime; 

      runtime.WorkflowStarted += runtime_WorkflowStarted; 
      runtime.WorkflowCreated += runtime_WorkflowCreated; 

      runtime.WorkflowUnloaded += runtime_WorkflowUnloaded; 
      runtime.WorkflowSuspended += runtime_WorkflowSuspended; 

      runtime.WorkflowCompleted += runtime_WorkflowCompleted; 
      runtime.WorkflowAborted += runtime_WorkflowAborted; 
      runtime.WorkflowTerminated += runtime_WorkflowTerminated; 
     } 
    } 

没有被触发，只有可以说我在这个特定的场景中引用运行时实例的方式是错误的。

任何人都知道一种方法来做到这一点？提前致谢。

WorkflowRuntime和WorkflowRuntimeBehavior是WF3工件，但您的问题被标记为WF4，所以我会推测您使用的是WF4。

在WF4中，执行此操作的方法是使用自定义TrackingParticipant并将其添加到WorkflowServiceHost的WorkflowExtensions集合中。
