我可以使用WorkflowApplication类运行WCF工作流服务吗？

Question

我想知道是否可以从文件加载xamlx wcf工作流并使用WorkflowApplication运行它？

期望的结果：

        using (Stream xaml = File.OpenRead("Service1.xamlx"))
        {
            activity = ActivityXamlServices.Load(xaml);
        }
        var workflowApplication = new WorkflowApplication(activity);
        workflowApplication.Run();

Answer 1

提取WorkflowService Root并在wfApp

上运行它

var svc = (WorkflowService)XamlServices.Load("c:\\path\\Service1.xamlx");
WorkflowApplication wfApp = new WorkflowApplication(svc.Body);
wfApp.Run();

仍然没有理解在WorkflowApplication中运行WorkflowService的原因。请记住，反向（带有作为WorkflowService的接收活动的运行活动工作流）是完全有效的。

Answer 2

未使用WorkflowApplication公开端点。请改用WorkflowServiceHost

WorkflowServiceHost host = new WorkflowServiceHost(activityLoadedFromXaml, baseAddress);
host.Description.Behaviors.Add(new System.ServiceModel.Description.ServiceMetadataBehavior() { HttpGetEnabled = true });
host.AddDefaultEndpoints();

host.Open();
