Public Property RevocationMode As X509RevocationMode

Property Value

Type: System.Security.Cryptography.X509Certificates.X509RevocationMode

One of the values in X509RevocationMode: NoCheck, Online, or Offline.

Exception Condition

Attempted to set when credential is read-only.

When using certificates, the system validates that the client certificate has not been revoked, by checking that the client certificate is not in the revoked certificate list.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.

The following code shows how to set this property.

Dim creds As New ClientCredentials()

' Configure chain trust.

creds.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.ChainTrust

creds.ServiceCertificate.Authentication.RevocationMode = X509RevocationMode.NoCheck

The property can also be set in a configuration file.
