WCF 4 : Fileless Activation Fails On XP (IIS 5) that has SSL port enabled

Question

我通过无文件激活在 XP 上的 IIS 中托管了一项服务。当没有为 IIS 启用 SSL 端口时服务启动正常，但当启用 SSL 端口时，我收到错误消息:

System.ServiceModel.ServiceActivationException: The service '/SkillsPrototype.Web/services/Linkage.svc' cannot be activated due to an exception during compilation. The exception message is: A binding instance has already been associated to listen URI 'http://rcollet.hsb-corp.hsb.com/SkillsPrototype.Web/Services/Linkage.svc'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config. . ---> System.InvalidOperationException: A binding instance has already been associated to listen URI 'http://rcollet.hsb-corp.hsb.com/SkillsPrototype.Web/Services/Linkage.svc'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config.

我的服务模型配置是

  <system.serviceModel>
    <diagnostics wmiProviderEnabled="true">
      <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" maxMessagesToLog="3000"/>
    </diagnostics>
    <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" />
      </webHttpEndpoint>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="false">

        <clear/>
        <add factory="System.ServiceModel.Activation.WebScriptServiceHostFactory" service="SkillsPrototype.ServiceModel.Linkage" relativeAddress="~/Services/Linkage.svc"/>
      </serviceActivations>
    </serviceHostingEnvironment>
  </system.serviceModel>

当您查看 svclog 文件时，会发现启用 SSL 时会返回两个基地址，一个用于 http，一个用于 https。我怀疑这是问题的一部分，但我不确定如何解决。

由于帖子的字符限制，我无法发布完整的服务日志。

据我所知，我花了几个小时解决了这个问题，并在发布后不久解决了这个问题。

问题似乎与使用 WebScriptServiceHostFactory 有关。相反，我创建了一个带有 kind 属性的服务条目，现在它可以工作了。

修改后的配置
