Namespace:  System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class ServiceCredentials : SecurityCredentialsManager, 

This class is used as a parameter in the BuildChannelListenerCore<TChannel> method, by methods of the ServiceCredentialsSecurityTokenManager, and is returned by the ServiceHostBase.Credentials property.

The following code shows how to override this class to implement custom service credentials.

public class MyServiceCredentials : ServiceCredentials
    X509Certificate2 additionalCertificate;

    public MyServiceCredentials()

    protected MyServiceCredentials(MyServiceCredentials other)
        : base(other)
        this.additionalCertificate = other.additionalCertificate;

    public X509Certificate2 AdditionalCertificate
            return this.additionalCertificate;
            if (value == null)
                throw new ArgumentNullException("value");
            this.additionalCertificate = value;

    public override SecurityTokenManager CreateSecurityTokenManager()
        return base.CreateSecurityTokenManager();

    protected override ServiceCredentials CloneCore()
        return new MyServiceCredentials(this);
