在Biztalk 2006 R2生成的WCF服务中扩展超时和消息大小

我正在使用Biztalk生成WCF服务。我得到的代码是:

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehaviorConfiguration">
          <serviceDebug httpHelpPageEnabled="true" httpsHelpPageEnabled="false" includeExceptionDetailInFaults="false" />
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" externalMetadataLocation="" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <!-- Note: the service name must match the configuration name for the service implementation. -->
      <service name="Microsoft.BizTalk.Adapter.Wcf.Runtime.BizTalkServiceInstance" behaviorConfiguration="ServiceBehaviorConfiguration">
        <endpoint name="HttpMexEndpoint" address="mex" binding="mexHttpBinding" bindingConfiguration="" contract="IMetadataExchange" />
        <!--<endpoint name="HttpsMexEndpoint" address="mex" binding="mexHttpsBinding" bindingConfiguration="" contract="IMetadataExchange" />-->
      </service>
    </services>
  </system.serviceModel>

也许它不是最漂亮的配置,但它可以工作。问题是我不知道如何修改超时和消息最大大小,因为它只有mex端点。我很惊讶这是如何工作在所有的只是mex端点。

1. 这到底是为什么?
