WCF 元数据不起作用

Question

我曾多次尝试让我的 WCF 服务公开 MetaData。相反，我一直保留异常(exception):

The contract name 'IMetadataExchange' could not be found in the list of contracts implemented by the service SecurityBroker. Add a ServiceMetadataBehavior to the configuration file or to the ServiceHost directly to enable support for this contract.

... 使用 IE 手动浏览服务时。

(我认为这与我的客户端应用程序无法生成服务引用的原因相同。婴儿步骤等等)

然而我的 web.config 看起来还不错:

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<behaviors>
    <endpointBehaviors>
        <behavior name="webHttpEnablingBehaviour">
            <webHttp />
        </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
        <behavior name="webHttpEnablingBehaviour">
            <serviceMetadata httpGetEnabled="true" />
        </behavior>
    </serviceBehaviors>
</behaviors>
<services>
    <service name="IWW.MIGTurbo2.WCF.Security.SecurityBroker">
        <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
        <endpoint address=""
            binding="webHttpBinding"
            bindingConfiguration="default"
            contract="IWW.MIGTurbo2.WCF.Security.ISecurityBroker"
                behaviorConfiguration="webHttpEnablingBehaviour">
        </endpoint>
    </service>
</services>
<client />
<bindings>
    <webHttpBinding>
        <binding name="default" />
    </webHttpBinding>
</bindings>
</system.serviceModel>

所以我有我的 IMetadataExchange 契约(Contract)定义为 墨西哥 很好，就我所见，连接起来了。我错过了一些愚蠢的东西吗？

编辑

我的服务定义如下所示，如果这有用的话:

<%@ ServiceHost Language="C#" Debug="true" Service="IWW.MIGTurbo2.WCF.Security.SecurityBroker" Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory"   %>

您的配置文件在“端点”元素上具有行为配置属性，但在“服务”元素上也需要它。
