如何在 VM 中使用托管在 windows 服务中的 WCF

Question

我对 WCF 及其配置没有足够的经验，我不知道如何解决这个问题。所以我很抱歉这个可能是愚蠢的问题。

我的虚拟机具有托管 WCF 的 windows 服务。我想从客户端运行ning 与此虚拟机运行的本地计算机上的此 WCF 通信。我可以运行本地服务没有问题，但是当涉及到与虚拟机上的服务通信时，我真的很难正确配置它。我想在不使用 IIS 的情况下使用 TCP 连接。

我尝试指定 VM 地址、备用地址和端点，但均未成功。你能告诉我什么是正确的配置吗？

<system.serviceModel>

<bindings>
  <netTcpBinding>
    <binding name="NetTcpBindingConfiguration">
      <security mode="None" />
    </binding>
  </netTcpBinding>
</bindings>

<services>
  <service behaviorConfiguration="WCFHostBehaviour" name="TestRunnerWCF.Service">
    <endpoint address="" binding="netTcpBinding" bindingConfiguration="NetTcpBindingConfiguration"
      name="WCFHostNetTcpEndpoint" contract="TestRunnerWCF.IService" />
    <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration=""
      name="WCFHostMexTcpEndpoint" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="net.tcp://192.168.10.25/Service" />
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="WCFHostBehaviour">
      <serviceMetadata httpGetEnabled="false" httpsGetEnabled="false" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

更新 1： 我不知道如何在我的客户中添加服务参考。如果我在我的本地机器上使用 localhost 我运行服务，这是不需要的。

Hyper-V 中的虚拟机运行，地址为 192.168.10.25。我可以从本地机器 ping 通它。我不使用任何端口转发。

我可以运行使用此配置的虚拟机上的客户端：

<system.serviceModel>
    <bindings>
        <netTcpBinding>
            <binding name="WCFHostNetTcpEndpoint">
                <security mode="None" />
            </binding>
        </netTcpBinding>
    </bindings>
    <client>
        <endpoint address="net.tcp://192.168.10.25/Service" binding="netTcpBinding"
            bindingConfiguration="WCFHostNetTcpEndpoint" contract="ServiceReference1.IService"
            name="WCFHostNetTcpEndpoint">
        </endpoint>
    </client>
</system.serviceModel>

但是当我尝试运行本地计算机上的客户端时，我无法连接到我的虚拟机。

正如 Reniuz 指出的那样，VM 中的防火墙阻止了我的连接。原评论：

So you need to specify VM's ip address. But first you need to ensure you can access it. Try to connect whit telnet . If you can't connect, first thing what you can do is to add inbound rule in VM's firewall (new rule-> select port->next-> enter wcf service port -> finish). Most likely the firewall is blocking in coming connection on your VM wcf port. – Reniuz
