Examples

The following code shows how to set this property.

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

// Create a binding that uses a certificate.
WSHttpBinding b = new WSHttpBinding(SecurityMode.Message);
b.Security.Message.ClientCredentialType =
    MessageCredentialType.Certificate;

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

// Configure ChainTrust with no revocation check.
myAuthProperties.CertificateValidationMode =
    X509CertificateValidationMode.ChainTrust;
myAuthProperties.RevocationMode = X509RevocationMode.NoCheck;

' Create a service host.
Dim httpUri As New Uri("http://localhost/Calculator")
Dim sh As New ServiceHost(GetType(Calculator), httpUri)

' Create a binding that uses a certificate.
Dim b As New WSHttpBinding(SecurityMode.Message)
b.Security.Message.ClientCredentialType = _
MessageCredentialType.Certificate

' Get a reference to the authentication object.
Dim myAuthProperties As X509ClientCertificateAuthentication = _
sh.Credentials.ClientCertificate.Authentication

' Configure ChainTrust with no revocation check.
myAuthProperties.CertificateValidationMode = _
X509CertificateValidationMode.ChainTrust
myAuthProperties.RevocationMode = X509RevocationMode.NoCheck

The property can also be set in a configuration file.

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

Remarks

When using certificates, the system validates that the client certificate is not revoked, by checking that the client certificate is not in the revoked certificate list. This check can be performed either by checking online or by checking against a cached revocation list. Revocation checking can be turned off by setting this property to NoCheck.
