Question

我有一个小型的WCF服务和客户端应用程序，当我在同一系统上运行它们时，它们可以正常工作，但是当我在单独的系统上运行它们时，却立即出现System.ServiceModel.CommunicationException失败。轨迹指示上述通道打开错误。这里会发生什么？

以下是需要注意的事项：

我正在Windows 7，.net 4.6.1上运行。
我在VS 2017中以管理员身份在调试模式下运行客户端和服务
我可以从客户端成功地在VS中“添加服务”。
服务运行时，我可以从客户端ping端口。
我正在使用net.tcp，但是更改为http不会改变结果。
两个系统上的Windows防火墙均已关闭。
两个系统上的Windows Defender均已关闭。
两个系统上均未运行防病毒软件。
在两个系统上都启用了端口共享。
我尝试了许多绑定和行为设置的变体，但都没有改变。
