WCF 没有端点侦听 net.pipe://localhost/Ivan.WCFService.Lib/Service1 可以接受消息

如何解决WCF 没有端点侦听 net.pipe://localhost/Ivan.WCFService.Lib/Service1 可以接受消息

我在windows服务中托管了一个WCF服务，在同一台电脑上实现跨进程访问。因此，采用了 netNamedPipBinding。现在，在我的开发 PC 中一切正常（客户端可以通过端点访问 wcf 服务）。但是当我将 client.exe、host.exe 和 wcf.dll 复制到另一台 PC 进行测试时。它不能工作并抛出这样的异常：

System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/Ivan.WCFService.Lib/MyService that Could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException,if present,for more details. ---> System.IO.PipeException: The pipe endpoint 'net.pipe://localhost/Ivan.WCFService.Lib/MyService' Could not be found on your local machine.
   --- End of inner exception stack trace ---

所以这里是问题：

是否有遗漏需要复制的文件。
异常指向端点。这是我的 wcf 服务库配置文件。

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <!-- When deploying the service library project,the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->

        <host>
          <baseAddresses>
            <add baseAddress="net.pipe://localhost/Ivan.WCFService.Lib"/>
          </baseAddresses>
        </host>
      </service>
    </services>

在我的情况下，我不确定 baseAddress 是否应该由“localhost”设置。并发布客户端配置文件。

                <security mode="Transport">
                  <transport protectionLevel="EncryptAndSign" />
                </security>
              </binding>
            </netNamedPipeBinding>
        </bindings>
        <client>
            <endpoint address="net.pipe://localhost/Ivan.WCFService.Lib/MyService"
                binding="netNamedPipeBinding" bindingConfiguration="NetNamedPipeBinding_IMyService"
                contract="MyServiceReference.IMyService" name="NetNamedPipeBinding_IMyService">
            </endpoint>
        </client>
    </system.serviceModel>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1"/></startup></configuration>

Win10 平台安全因素是否会影响此类端点？（已以管理员身份运行）
已经开启net.pip Listener Adapter服务，状态为running。总之，这对配置文件可以在我的开发 PC 中正常运行。当我尝试在其他 PC 上对其进行测试时，它不会引发端点异常。有人可以帮忙吗？

解决方法

需要修改baseAddress：

           <endpoint address="net.pipe://The IP address of the WCF server/Ivan.WCFService.Lib/MyService"
                binding="netNamedPipeBinding" bindingConfiguration="NetNamedPipeBinding_IMyService"
                contract="MyServiceReference.IMyService" name="NetNamedPipeBinding_IMyService">
            </endpoint>

如果客户端和服务器在同一台机器上，我们可以使用localhost。如果客户端和服务器不在同一台机器上，我们需要修改客户端的端点地址。如果此时客户端的访问端点地址还是 localhost 会报错。

需要修改客户端的端点地址，使其与WCF服务器的IP地址一致，然后重新编译。
