Setting binding in WCF service - wcf

Question

This may seem like a really easy question but I can't seem to figure it out at all.
I'm trying to create a new WCF service, and I'm new to having to secure them. I'm using a custom username/password for authentication. The problem [right now anyways] that I seem to be running into is that I can't figure out how to define the service to use the WSHttpBinding (on the service side, not the client side).
Am I missing something incredibly simple? Any pointers and/or recommendations would be greatly appreciated!
EDIT
Here's my code so far:
IAccountService
[ServiceContract]
public interface IAccountService
{
[OperationContract]
bool IsCardValid(string cardNumber);
[OperationContract]
bool IsAccountActive(string cardNumber);
[OperationContract]
int GetPointBalance(string cardNumber);
}

{
static void Main(string[] args)
{
Console.WriteLine("Please enter card number");
var number = Console.ReadLine();
var endPoint = new EndpointAddress("http://localhost:59492/Account/AccountService.svc");
var binding = new WSHttpBinding(SecurityMode.Message);
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
var cf = new ChannelFactory<IAccountService>(binding, endPoint);
cf.Credentials.UserName.UserName = "testuser";
cf.Credentials.UserName.Password = "Password1!";
var service = cf.CreateChannel();
var balance = service.IsAccountActive(number);
Console.WriteLine("\nBALANCE: {0:#,#}", balance);
Console.Write("\n\nPress Enter to continue");
Console.Read();
}
}

Answer 1

You need to define the abc (address, binding, contract) configuration into de web.config file (you can also do it programmatically. the b part, the binding, you can specify the wsHttpBinding
<system.serviceModel>
<services>
<service name = "MyNamespace.MyService">
<endpoint
address = "http://localhost:8000/MyService"
binding = "wsHttpBinding"
contract = "MyNamespace.IMyContract" />
</service>
</services>
</system.serviceModel>
If you wish to enable security in a proper way, there is a lot of literature and options. You can use certificates, windows based, tokens, ... passing a username & password like a parameter could not be the best way to do it.

Answer 2

There is an extensive sample on MSDN (How to: Specify a Service Binding in code) - but basically, you need to have:
your service contract (IMyService)
an implementation of that service (MyService)
a code where you create your ServiceHost to host your service
You got all of that? Great!
In that case, just do something like this:
// Specify a base address for the service
string baseAddress = "http://YourServer/MyService";
// Create the binding to be used by the service.
WsHttpBinding binding1 = new WsHttpBinding();
using(ServiceHost host = new ServiceHost(typeof(MyService)))
{
host.AddServiceEndpoint(typeof(IMyService), binding1, baseAddress);
host.Open();
Console.ReadLine();
}
and now you should have your service host up and running, on your chosen base address and with the wsHttpBinding defined in code.
