Property Value

SslProtocols

Returns SslProtocols.

Examples

NetTcpBinding b = new NetTcpBinding();  
b.Security.Mode = SecurityMode.Transport;  
b.Security.Transport.ClientCredentialType = TcpClientCredentialType.Certificate;  
b.Security.Transport.SslProtocols = SslProtocols.Tls11 | SslProtocols.Tls12;  
EndpointAddress a = new EndpointAddress("net.tcp://contoso.com/TcpAddress");  
ChannelFactory<ICalculator> cf = new ChannelFactory<ICalculator>(b, a);  
cf.Credentials.ClientCertificate.SetCertificate(  
    StoreLocation.LocalMachine,  
    StoreName.My,  
    X509FindType.FindByThumbprint,  
    "0000000000000000000000000000000000000000");

Remarks

The default value is Ssl3 | Tls | Tls11 | Tls12. Versions of the framework prior to 4.6 only support Ssl3 and Tls. If these are not included, communication with earlier versions of the framework will not be possible. Specifying Tls11 and/or Tls12 will disable the usage of Ssl3, even if it has been included.
