【中文标题】在从 net.tcp 协议连接到 WCF 的端点处侦听的问题【英文标题】：Issue with Listening at an Endpoint connecting to WCF from net.tcp protocol 【发布时间】：2020-08-24 22:18:00 【问题描述】：这个奇怪的错误是在发布这篇文章的前一天出现的。以前它工作正常，但现在不行。
在一次重新启动系统的动作中，错误消失并且能够访问应用程序。
再次重启系统后，错误开始出现，不知道根本原因。
启用的协议：net.tcp,http
我可以浏览下面的链接
http://localhost/TAServices/AuthenticationManager.svc http://username.domainname.com/TAServices/AuthenticationManager.svc?wsdl http://username.domainname.com/TAServices/AuthenticationManager.svc?singleWsdl下面是导致异常的sn-p
objCheckUserLoginResponse = AuthenticationManagerClient.Check(objCheckUserLoginRequest, objCustomer);
例外：
The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/TAServices/AuthenticationManager.svc' is unavailable for the protocol of the address.
System.ServiceModel.EndpointNotFoundException: The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/TAServices/AuthenticationManager.svc' is unavailable for the protocol of the address.

在不知道原因的情况下，我什么也做不了。
请建议解决 EndpointNotFoundException 问题 wrt 到代码或从 Windows 10 (1903)
【问题讨论】：
您在哪里配置了服务的端点？我没有在配置文件中看到 【参考方案1】：在英特尔® 显卡驱动程序更新启动后，我通过释放占用端口808 的OneApp.IGCC.WinService.exe 解决了这个问题。但这听起来很奇怪，所以请检查SMSvcHost.exe 是否列在808 端口。
C:\Windows\system32>netstat -ano | find "808"
TCP 0.0.0.0:808 0.0.0.0:0 LISTENING 4356
TCP [::]:808 [::]:0 LISTENING 4356
C:\Windows\system32>tasklist | find "5156"
SMSvcHost.exe 5156 Services 0 5,604 K
如果您发现列出的进程名称不是SMSvcHost.exe，例如OneApp.IGCC.WinService.ex 或其他名称，请继续执行这些步骤，否则在此停止。
所以在我的情况下，名称为OneApp.IGCC.WinService.ex 的进程占用了端口808，其唯一进程ID 为5068
从提升的提示符处执行命令TASKKILL /F /PID <ProcessId>。
C:\Windows\system32>netstat -ano | find "808"
TCP 0.0.0.0:808 0.0.0.0:0 LISTENING 5068
TCP [::]:808 [::]:0 LISTENING 5068
C:\Windows\system32>tasklist | find "5068"
OneApp.IGCC.WinService.ex 5068 Services 0 36,632 K
C:\Windows\system32>taskkill /F /PID 5068
SUCCESS: The process with PID 5068 has been terminated.
C:\Windows\system32>netstat -ano | find "808"
C:\Windows\system32>
然后从services.msc重启Net.Tcp Port Sharing Service
即使在重新启动系统后OneApp.IGCC.WinService.exe 也会通过监听808 端口来覆盖SMSvcHost.exe。所以禁止从services.msc运行Intel(R) Graphics Command Center Service (C:\Windows\System32\DriverStore\FileRepository\igcc_dch.inf_amd64_26b207b939eae50e)
【讨论】：
将启动选项设置为自动（延迟启动）是否也有帮助？ 我也遇到了这个问题。您是否尝试将启动选项设置为延迟启动，这有帮助吗？【参考方案2】：您似乎在 IIS 中托管 WCF 服务项目并尝试使其在 HTTP 和 Nettcp 上工作。为了让它在 NetTcp 协议上工作，我们应该在 IIS 站点绑定模块中启用某些 Window 功能和 NetTcp 绑定。此外，我们应该使用 Nettcpbinding 配置服务端点，这在您的 Webconfig 文件中没有设置。
请考虑将System.servicemodel 部分替换为以下配置。
<system.serviceModel>
<services>
<service name="WcfService1.Service1">
<endpoint address="service1" binding="basicHttpBinding" contract="WcfService1.IService1" ></endpoint>
<endpoint address="service2" binding="netTcpBinding" contract="WcfService1.IService1"></endpoint>
<endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"></endpoint>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding>
<security mode="Transport">
<transport clientCredentialType="None"></transport>

</binding>
</basicHttpBinding>
<netTcpBinding>
<binding>
<security mode="None"></security>
</binding>
</netTcpBinding>

<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
</system.serviceModel>
为了在 IIS 中支持 Net.tcp 协议，请启用以下 windows 功能。 随后，在网站上添加 Net.tcp 支持。 最后，使用 net.tcp 协议添加站点绑定。注意，808 是 net.tcp 协议的默认端口。不要使用其他网站已经使用的端口号。 请参考以下链接。Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Base address schemes are [http] 如果问题仍然存在，请随时告诉我。
