我使用添加服务引用创建了使用旧 asmx Web 服务（已托管在网络服务器上）的示例 Web 应用程序。当我在 Visual Studio 2012 中运行此应用程序时，它已经创建了端点、basicHttpBinding 等，没有额外的设置，它可以工作。在我发布它并将其托管在 IIS 上之后，它给出了一个错误，如下所示：

现有连接被远程主机强行关闭 说明：当前 Web 请求执行过程中出现未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详细信息：System.Net.Sockets.SocketException：现有连接被远程主机强行关闭

源错误：

在执行当前 Web 请求期间生成了未处理的异常。可以使用下面的异常堆栈跟踪来识别有关异常起源和位置的信息。
