无法建立连接，因为目标计算机已主动拒绝127.0.0.1:8000

我已经创建了WCF服务，并尝试在托管Windows服务中托管（后面的文章）。该服务已启动并在服务中运行。

当尝试在客户端应用程序（net。tcp://localhost:8000/UserManagement)我得到错误：

元数据包含无法解析的引用：’net。tcp://localhost:8000/UserManagement"。无法连接到网tcp://localhost:8000/UserManagement.连接尝试持续时间跨度为00:00:00.95 31433。TCP错误代码10061:否由于目标计算机主动拒绝，无法建立连接它127.0.0.1:8000。由于目标机器主动拒绝127.0.0.1:8000如果定义了服务在当前解决方案中，尝试构建解决方案并添加再次提供服务参考。
