WCF服务实例化客户端时出现keynotfound错误

Question

       

在客户端调用WCF服务，并实例化client时，在Reference.cs文件的public UserServiceClient() {}出跳出keynotFfound错误，为什么啊？

Answer 1

引用服务完成后还有如下警告：

警告 1 自定义工具警告: Endpoint 'WSHttpBinding_UserService' at address 'http://localhost/UserService' is not compatible with Silverlight 3. Skipping... 

警告 2 自定义工具警告: No endpoints compatible with Silverlight 3 were found. The generated client class will not be usable unless endpoint information is provided via the constructor. 

Answer 2

还有就是ServiceReferences.ClientConfig文件里只有一个</configuration>标记，这是发生什么错误了吗？

Answer 3

在对ServiceReferences.ClientConfig文件做了简单配置后，又显示如下错误：

Could not find default endpoint element that references contract 'UserService.IUserService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

配置如下：

<configuration>
  <system.serviceModel>
    <client>

      <endpoint address="http://localhost/UserService"
                binding="wsHttpBinding"
                contract="NotificationService.IUserService" />
    </client>
  </system.serviceModel>
< /configuration>

Answer 4

把contract改为UserService.IUserService后，（‘UserService’是添加引用时自己改的名称）又回到了keynotfound错误

Answer 5

添加bindingConfiguration后能正常实例化了，如下。但我客户端是basicHttpBinding,服务端是wsHttpBinding,这样也可以？帮忙解释一下啊~

还有就是我服务端也没有bindingConfiguration啊，为什么客户端非要要呢？这个是干嘛的？

<configuration>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IService1" closeTimeout="00:01:00"
            openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
            maxBufferSize="65536" maxReceivedMessageSize="65536"
            textEncoding="utf-8">
          <security mode="None"/>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>

      <endpoint address="http://localhost/UserService"
                bindingConfiguration="BasicHttpBinding_IService1"
                binding="basicHttpBinding"
                contract="UserService.IUserService" />
    </client>
  </system.serviceModel>
</configuration>

Answer 6

引用服务完成后还有如下警告：

警告 1 自定义工具警告: Endpoint 'WSHttpBinding_UserService' at address 'http://localhost/UserService' is not compatible with Silverlight 3. Skipping... 

警告 2 自定义工具警告: No endpoints compatible with Silverlight 3 were found. The generated client class will not be usable unless endpoint information is provided via the constructor. 

你检查下 配置文件里有这个 名字的 定义嘛 WSHttpBinding_UserService

在不同应用程序类型中，不一定支持所有的binding,像windows phone貌似只支持basicHttpBinding，我当是在服务端使用的是wsHttpBinding，所以引用时不能生成完整的客户端config文件，所以也就出现keynotFound异常
