X509ClientCertificateAuthentication Class

Specifies authentication properties for validating the client certificate.

Namespace: System.ServiceModel.Security
Assembly: System.ServiceModel (in system.servicemodel.dll)

public class X509ClientCertificateAuthentication
public class X509ClientCertificateAuthentication
public class X509ClientCertificateAuthentication
Not applicable.

If the CertificateValidationMode is set to Custom, then you must create a custom certificate validator that inherits from the X509CertificateValidator class. For more information, see How To: Create a Service Employing a Custom Certificate Validator.

The following code illustrates setting this property.

// Create a service host.
Uri httpUri = new Uri("http://localhost/Calculator");
ServiceHost sh = new ServiceHost(typeof(Calculator), httpUri);

// Get a reference to the authentication object.
X509ClientCertificateAuthentication myAuthProperties =
    sh.Credentials.ClientCertificate.Authentication;

// Configure peer trust.
myAuthProperties.CertificateValidationMode =
    X509CertificateValidationMode.PeerTrust;
// Configure chain trust.
myAuthProperties.CertificateValidationMode =
    X509CertificateValidationMode.ChainTrust;
// Configure custom certificate validation.
myAuthProperties.CertificateValidationMode =
    X509CertificateValidationMode.Custom;

// Specify a custom certificate validator (not shown here) that inherits 
// from the X509CertificateValidator class. 
// creds.ClientCertificate.Authentication.CustomCertificateValidator =
//    new MyCertificateValidator();

The property can also be set in a configuration file.

<serviceCredentials>
  <clientCertificate>
     <authentication certificateValidationMode='ChainTrust' />
  </clientCertificate>
</serviceCredentials>
