In order to have SessionId, you have to have Session-enabled binding. For example, wsHttpBinding. In your config file, you should have something like:

In the IMyService interface, you have to have SessionMode attribute set to Required, like so:

[ServiceContract(SessionMode = SessionMode.Required)]
public interface IMyService
{
    [OperationContract]
    AuthenticationData Authenticate(string username, string password);
}

When all of this is setup, you can get to the SessionId like this:

var sessionId = OperationContext.Current.SessionId;

Another way would be to enable AspNetCompatibilityRequirements but it's a bit of an overkill just to get the SessionId.
