Question

我创建了WCF服务并尝试在托管Windows服务中托管（遵循article）。该服务已在服务中启动并运行。

尝试在客户端应用程序中添加URL时（net.tcp：// localhost：8000 / UserManagement）我收到错误：

元数据包含无法解析的引用： '的net.tcp：//本地主机：8000 / UserManagement'。无法连接到的net.tcp：//本地主机：8000 / UserManagement。连接尝试持续了时间跨度为00：00：00.9531433。 TCP错误代码10061：否可以建立连接，因为目标机器主动拒绝它127.0.0.1:8000。由于目标，无法建立连接机器主动拒绝它127.0.0.1:8000如果服务已定义在当前的解决方案中，尝试构建解决方案并添加服务参考。

    public bool AddUser(string strName, DateTime dtDOB, string strGender, string strRole)

    public static void Main()

Answer 1

您需要使用地址

net.tcp://localhost:8000/UserManagement/mex

配置服务参考时。

或者，您的元数据端点应使用mexHttpBinding，并且应在服务行为中将httpGetEnabled设置为true

<serviceMetadata httpGetEnabled="true"/>

Answer 2

在您提供的MSDN链接后，我也遇到了同样的问题。该代码中存在错误。

在OnStart方法中，

serviceHost = new ServiceHost(typeof(UserManagementService));

而不是为UserManagementService创建ServiceHost，请在此处使用您的实际WCF服务类名称。这行代码将创建一个Windows服务实例，而不是WCF服务。我能够使用它来修复我的。

无法建立连接，因为目标计算机主动拒绝它127.0.0.1:8000
