Question

我没有足够的WCF及其配置经验，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。我想从运行此虚拟机的本地计算机上运行的客户端与此WCF进行通信。我可以在本地运行该服务没有问题，但是当涉及与虚拟机上的服务进行通信时，我真的很难配置它。我想在不使用IIS的情况下使用TCP连接。

我尝试指定VM的地址，备用地址和端点但没有成功。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端添加服务引用。如果我使用localhost，我在本地计算机上运行服务，这是不可取的。

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

我可以使用此配置在虚拟机上运行客户端：

<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>

但是当我尝试在本地计算机上运行客户端时，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：

因此您需要指定VM的IP地址。但首先，您需要确保可以访问它。尝试连接whit telnet。如果您无法连接，首先您可以做的是在VM的防火墙中添加入站规则（新规则 - >选择端口 - ＆gt; next-＆gt;输入wcf服务端口 - ＆gt;完成）。很可能防火墙在您的VM wcf端口上阻止连接。 - Reniuz
