Wcf 输入字符串的格式不正确

我只是创建了一个wcf服务，它正在打印“hello world”。创建了顺序控制台工作流，向工作流中添加了发送活动和代码活动。此处引用了该服务。已配置发送活动。已为返回值创建依赖项属性

现在当我运行应用程序时。它在行的

program.cs

文件中抛出格式异常

WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(Using_SendActivity.Workflow1));

我哪里出错了

我正在使用的wcf文件：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WcfServiceForSendActivity
{
    // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in App.config.
    public class Service1 : IService1
    {
        #region IMyService Members

        public string GetResponse()
        {
            return string.Format("Hello World !!!");
        }

        #endregion

    }
}

在Win7上，从提升的命令提示符运行“lodctr/R”，然后重新启动以重新加载性能计数器
