c# - 将跟踪配置文件添加到工作流

Question

我有我的自定义工作流程，如下所示。如何添加工作流跟踪配置文件以监控每个步骤中发生的情况？

 static void Main(string[] args)
    {
        OuputToConsole("hello", "wf");

        Console.ReadKey();
    }

    private static void OuputToConsole(string p, string p_2)
    {
        // workflow implementation

        var s = new Sequence()
                    {
                        Activities =
                            {
                                new WriteLine() {Text = p},
                                new WriteLine() {Text = p_2}
                            }
                    };

        // running code or execute code
        WorkflowInvoker.Invoke(s);
    }

您可以参考 WCf_WF_sample 进行跟踪。你可以从这里下载。
