Question

我有一个WCF服务已运行多年，我经常更新/添加。我通常在部署到生产服务器之前从VS内测试服务。我最近尝试添加一个新的端点，如this（DeliveryReport），接口和实现：

[ServiceContract (Namespace = "carsweb.no/")]
    public interface IService1
    {
        [OperationContract]
        [WebInvoke]
        string DeliveryReport(string s);

        //[OperationContract]
        //string GetData(string value); several here....

  public class Verksted : IService1
    {
        public string DeliveryReport(string rep)
        {
            return "You posted " + rep;
        }

然后VS中的WCF测试客户端拒绝添加该服务并给我这条消息：＆＃34;无法添加服务。可能无法访问服务元数据。确保您的服务正在运行并公开元数据。＆＃34; 然后，我评论了所有我的更改（不是很多），同样删除了对ServiceModel.Web＆＃39;的引用。我不得不补充一下。但是在启动WCF测试客户端时我仍然会遇到相同的错误，尽管一切都和以前一样。没有对配置进行任何更改（我已经检查过）。之前和之后的配置是相同的：

我几天前尝试制作一些其他的WCF服务，我得到了同样的消息。这是与网络，我的电脑，我的VS环境或什么？我完全卡住了！

WCF服务突然拒绝在VS2017调试中启动
