WcfTestClient:合同'IMetadataExchange‘错误

Question

我创建了WCF服务应用程序--在运行WcfTestClient之前没有错误。它需要配置IMetadataExchange。

如何配置或避免使用IMetadataExchange？

错误：

-客户端配置中的合同'IMetadataExchange‘与服务合同中的名称不匹配，或者这份合同中没有有效的方法。若要恢复，请手动更正客户端配置。

或还原到默认配置。

或者在Tools -> Options菜单中检查“启动服务时总是重新生成配置”，然后刷新服务。

Answer 1

在您的配置中，这显然是错误的：

<endpoint address="mex" binding="mexHttpBinding" contract="WcfCrmService.IPermitTypesService" />

用于元数据交换的MEX端点必须是，必须具有WCF内建契约IMetadataExchange和，而不是您自己的服务契约。

试着使用以下方法：

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

现在起作用了吗？？WCF测试客户端将使用MEX端点来了解您的服务--如果您在那里有错误的服务合同，测试客户机肯定不会工作.

更新：您选择的基本地址也有点奇怪：

<baseAddresses>
   <add baseAddress="http://localhost:8732/Design_Time_Addresses/WcfCrmService/Mex/" />
</baseAddresses>

这意味着:您的实际服务可以访问：

http://localhost:8732/Design_Time_Addresses/WcfCrmService/Mex/

当您的MEX端点在以下位置到达时：

http://localhost:8732/Design_Time_Addresses/WcfCrmService/Mex/mex/

我建议为服务使用更好/更有意义的基址，只需将mex添加到MEX端点的末尾：

<baseAddresses>
   <add baseAddress="http://localhost:8732/Services/WcfCrmService/" />
</baseAddresses>
