C# 使用TCP承载多个端点的WCF

我在WCF上托管多个端点时遇到问题，这给了我错误：

System.ServiceModel.AddressalReadyUseException:已存在一个 IP端点上的侦听器 0.0.0.0:808. 如果有另一个应用程序正在侦听此端点，或者您有多个服务端点，则可能会发生这种情况 在具有相同IP端点但不兼容的服务主机中 绑定配置。-->System.Net.Sockets.SocketException:仅限 每个套接字地址（协议/网络地址/端口）的一种用法是 通常允许在system.Net.Sockets.Socket.DoBind（端点 endPointSnapshot，SocketAddress（SocketAddress）

I'm having separate services with callbacks. Please advise.

WindowsService:


问题似乎出在您的MEX端点上——它们在两个服务之间是相同的。尝试为他们提供不同的地址，看看这是否解决了问题。
我的第一个猜测是，您有另一个应用程序在某个端口上侦听，请尝试将端口更改为类似的内容
在两个端口上尝试不同的端口

  <add baseAddress="net.tcp://localhost:2200/CalculatorService" />
 <add baseAddress="net.tcp://localhost/MyWorldService:2200" />

在我的例子中，我已经更新了.net framework，并且收到了这个错误。我通过删除配置文件中的listenBacklog和maxConnections属性来解决此错误

是解决我的问题的解决方案。
有了它，我可以让WCF与测试客户端一起运行。但是，当我在windows服务中托管此服务时，我无法使用svcutil下载元数据。您可以准确地发布您对.config文件的修改方式，以及尝试对该服务使用svcutil时收到的错误消息吗？请检查我的编辑。当我通过服务管理器运行服务时，我使用svcutil测试服务，它还下载元数据。它说：无法从网络获取元数据。tcp://localhost/CalculatorService. 第二个endpointAFischbein的解决方案也是如此，但由于它托管在windows服务中，因此我无法从svcutil下载元数据
