WcfTestClient:合约 '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 IMetadataExchange进行配置。

如何配置IMetadataExchange或避免使用？

错误:

--------------------------- Microsoft WCF Test Client
--------------------------- The contract 'IMetadataExchange' in client configuration does not match the name in service contract, or there is no valid method in this contract. To recover, please manually correct client configuration.

Or restore to default configuration.

Or check "Always regenerate config when launching services" in the Tools -> Options menu, then refresh the service.

App.config

Answer 1

这在您的配置中绝对是错误的:

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

用于元数据交换的 MEX 端点 必须有 WCF 内置合约 IMetadataExchange和 不是 您自己的服务契约(Contract)。

尝试使用这个:

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

这现在有效吗？？ 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契约(Contract)，测试客户端肯定不会工作......

更新:您选择的基地址也有点奇怪:

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

这意味着:您的实际服务可在以下位置访问:

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

当您到达 MEX 端点时:

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

我建议为服务使用更好/更有意义的基地址，只需添加 mex到 MEX 端点的末尾:

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