Question

我是wcf.i的新手，有简单的wcf服务，用于添加，减法，多重，分区等计算器。我的服务配置文件中有两个端点。一个是basicHttpBinding，另一个是netTcpBinding。当我点击f5然后wcf测试客户端出现并显示错误 wcf无法添加服务。服务元数据可能无法访问但如果我关闭netTcpBinding和mex for netTcpBinding并按f5，那么wcf测试客户端可以调用该服务。这是我的配置条目。所以，请看看，告诉我为什么我收到netTcpBinding错误以及如何解决它。

        </behaviors>

请指导我在配置文件中修复的位置，因此不应该出现我使用的任何绑定问题。感谢

我认为......如果你有两个“IMetadataExchange”端点，那么你需要提供不同的地址。例如：

        <service name="MyTcpActivation.CalculatorService" behaviorConfiguration="CalculatorServiceBehavior">

            <endpoint address="" binding="netTcpBinding" bindingConfiguration="PortSharingBinding" contract="MyTcpActivation.ICalculator"/>
            <endpoint address="mex1" binding="mexTcpBinding" contract="IMetadataExchange"/>

            <endpoint address="" binding="basicHttpBinding" contract="MyTcpActivation.ICalculator" />
            <endpoint address="mex2" binding="mexHttpBinding" contract="IMetadataExchange"/>             
        </service>

wcf无法添加服务。服务元数据可能无法访问
