WCF服务和客户端配置文件

Question

我是wcf的新手所以经常从各个网站上阅读很多关于wcf的文章。最近我看到了一个wcf聊天代码，看到了服务端和客户端的配置代码差异。

是否必须提供服务端＆amp;客户端配置应该在配置设置方面看起来类似。

这里我粘贴了两个配置代码，告诉我为什么在服务和配置设置中有所不同？客户端？

服务端配置详细信息

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <services>
            <service name="ChatSvc.ChatService" behaviorConfiguration="ChatServiceBehavior">
                <endpoint address="net.tcp://localhost:8085/Chat" binding="netTcpBinding" 
                    contract="ChatSvc.IChat" />
                <!--bindingConfiguration="PortSharingBinding"-->

                <endpoint address="net.tcp://localhost:8085/Chat/mex"
                          binding="mexTcpBinding" contract="IMetadataExchange"/>
            </service>
        </services>
        <!--<bindings>
            <netTcpBinding>
                <binding name="PortSharingBinding" portSharingEnabled="true">

                </binding>
            </netTcpBinding>
        </bindings>-->
        <behaviors>
            <serviceBehaviors>
                <behavior name="ChatServiceBehavior">
                    <serviceMetadata httpGetEnabled="false"/>
                    <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>

    </client>
  </system.serviceModel>
</configuration>

现在我的问题是客户端有这么多设置，但服务端的设置很少.....怎么可能。服务是否正常运作？

我是wcf的新手。所以请详细指导我。感谢。

客户端配置中的大部分过剩意味着WCF诊断已经为客户端启用了一个点。

例如，客户端配置的整个<system.diagnostics>部分完全是可选的，可以删除。
