Es wird in einem Intranet mit IIS 7 ausgeführt und funktioniert einwandfrei, wenn ich die anonyme Authentifizierung im IIS-Manager aktiviere. Wenn ich es deaktiviere und versuche, es mit wcftestclient auszuführen, wird die folgende Fehlermeldung angezeigt:

<code>Error: Cannot obtain Metadata from http://myserver/testing/eval.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.  For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error    URI: http://myserver/testing/eval.svc    Metadata contains a reference that cannot be resolved: 'http://myserver/testing/eval.svc'.    The HTTP request is unauthorized with client authentication scheme 'Anonymous'. 
</code>

Dies ist meine web.config-Datei,

<code><system.serviceModel>
<bindings>
    <wsHttpBinding>
        <binding name="Binding1">
            <security mode="Transport">
                <transport clientCredentialType="Windows" />
                <message establishSecurityContext="true" />
            </security>
        </binding>
    </wsHttpBinding>
    <basicHttpBinding>
        <binding name="httpBinding">
            <security mode="Transport">
                <transport clientCredentialType="Windows" />
            </security>
        </binding>
    </basicHttpBinding>     
</bindings>

<services>
  <service behaviorConfiguration="ServiceBehavior" name="EvalServiceLibrary.EvalService">
    <endpoint address="" binding="wsHttpBinding" bindingConfiguration="Binding1" contract="EvalServiceLibrary.IEvalService">
      <identity>
        <dns value="myserver.mydomain.com" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <endpoint address="basic" binding="basicHttpBinding" contract="EvalServiceLibrary.IEvalService" />
  </service>
</services>

<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior">
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true" />
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>
</code>

Wie Sie sehen, fülle ich Metadaten mit mexHttpBinding-Endpunkten auf. Daher ist jeder Rat willkommen.

Vielen Dank, m0dest0.
