EF+WCF查询不到数据

[华夏微环境-袁皓-18200401756]

单独运行服务端，使用vs的wcf测试客户端，ef可以查到数据。但是在客户端调用服务就查不到数据了。
服务端查询代码

 public  class TestService
    {
        private WcfServerConnection db = new WcfServerConnection();
        public List<TestData> GetList()
        {

            var persons = from p in db.TestEntitys
                          select new TestData
                          {
                              ID = p.ID, Conten = p.Content

                          };


           var ulits = persons.ToList();
            return ulits;
        }
    }

客户端调用

   public string Test()
        {
            EndpointAddress edpHttp = new EndpointAddress("http://localhost:57840/");

            ClientFactory client = new ClientFactory(new WSHttpBinding(SecurityMode.None), edpHttp);

            string temp = client.GetTest().ToString();
            return temp;
         

        }

 public  class ClientFactory:ClientBase<ITest>,ITest
    {
        public ClientFactory(System.ServiceModel.Channels.Binding binding, EndpointAddress edpAddr)
            : base(binding, edpAddr) { }

        public void WcfTest() {
            ;
        }

        public List<TestData> GetTest()
        {
            return base.Channel.GetTest();
        }

     

    }

客户端调用查询，调试发现 var ulits = persons.ToList(); 没有数据，count=0

http://localhost:57840/ 路径对吗？你设置了默认文档的么
