Configuring a WCF Binding for https

Both BasicHttpBinding and WSHttpBinding support Transport Security (https). However, neither do it by default. The binding must be configured correctly. Here is how to do it in code:

BasicHttpBinding binding = new BasicHttpBinding();
binding.Security.Mode = BasicHttpSecurityMode.Transport;

or simply

BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);

For WSHttpBinding:

WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.
TransportWithMessageCredential;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;

Here is a summary of the System-provided Bindings. Note that the NetTcp bindings have Transport security (encryption) enabled by default.
