无法识别的元素 'security'

Unrecognized element 'security'

我编写了一个 RESTful WCF 服务,该服务又调用第三方 SOAP 网络服务。

我收到以下错误:无法识别的元素 'security'

我的配置文件如下所示:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
    <add key="DbServer" value=""/>
    <add key="DbName" value=""/>
    <add key="DbUser" value=""/>
    <add key="DbPassword" value=""/>
</appSettings>
<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="VoicePortalSupportServicesSoap" />
    <security mode="TransportCredentialOnly">
      <transport clientCredentialType="Basic" realm="ctagsd1"/>
    </security>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://ctagsd1/abc.asmx"
    binding="basicHttpBinding" bindingConfiguration="VoicePortalSupportServicesSoap"
    contract="VoicePortalSupportServices.VoicePortalSupportServicesSoap"
    name="VoicePortalSupportServicesSoapEndpoint" />
</client>
<services>
  <service name="abc">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8787/abc"/>
      </baseAddresses>
    </host>
  </service>
</services>

主机代码最少。我收到错误消息:host.Open();

堆栈跟踪看起来像:

绑定声明如下

<bindings>
  <basicHttpBinding>
    <binding name="VoicePortalSupportServicesSoap">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" realm="ctagsd1"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
