Transport Security with Certificate Authentication

Question

I'm getting the following error when I access my webservice localhost/MyService/MyService.svc

The SSL settings for the service 'SslRequireCert' does not match those of the IIS 'Ssl, SslNegotiateCert'.

I've following the web.config examples as specified in http://msdn.microsoft.com/en-us/library/ms731074.aspx

Here is my wcf server web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
  <appSettings />
  <system.web>
    <identity impersonate="false" />

    <authentication mode="Windows" />
    <customErrors mode="Off" />
    <webServices>
      <protocols>
        <add name="HttpGet" />
        <add name="HttpPost" />

  <system.serviceModel>
    <services>
      <service name="AspNetSqlProviderService" behaviorConfiguration="MyServiceBehavior">
        <endpoint binding="wsHttpBinding" contract="Interface1" bindingConfiguration="CertificateWithTransportWSHttpBinding" />
        <endpoint binding="wsHttpBinding" contract="Interface2" bindingConfiguration="CertificateWithTransportWSHttpBinding" />
        <endpoint address="mex" binding="wsHttpBinding" bindingConfiguration="CertificateWithTransportWSHttpBinding" name="Metadata_Exchange" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceBehavior">
          <serviceDebug includeExceptionDetailInFaults="True" />
          <serviceMetadata />
          <serviceCredentials>
            <clientCertificate>
              <authentication trustedStoreLocation="LocalMachine"
                               revocationMode="Online"/>
            </clientCertificate>
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding>
        <binding name="CertificateWithTransportWSHttpBinding">
          <security mode="Transport">
            <transport clientCredentialType="Certificate" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

I've configured IIS as follows:

• https binding added using self signed certificate
• Under SSL settings, require SSL and accept client certificates is checked
• The self signed certificate has been added to the Local Computer Trusted Root CA.

I can browse and execute the .asmx service definition, but the .svc gives me the error described above.

Try to comment out your mex endpoint. That should get it working
