NetNamedPipeBinding is optimized for communication between different
processes on the same system.
The binding NetMsmqBinding brings queued communication to WCF.
Here, the messages are sent to the message queue.
MsmqIntegrationBinding is the binding for existing applications that uses
message queuing. In contrast, the binding NetMsmqBinding requires WCF
applications both on the client and server.
With a CustomBinding the transport protocol and security requirements can
be completely customized.
Depending on the binding, different features are supported. The bindings starting with WS are platformindependent,
supporting Web services specifications. Bindings that start with the name Net use binary
formatting for high-performance communication between .NET applications. Other features are support
of sessions, reliable sessions, transactions, and duplex communication; the following table lists the bindings
supporting these features.

Along with defining the binding, the service must define an endpoint. The endpoint is dependent on the
contract, the address of the service, and the binding. In the following code sample, a ServiceHost object
is instantiated, and the address http://localhost:8080/RoomReservation, a WsHttpBinding instance,
and the contract are added to an endpoint of the service:
static ServiceHost host;
static void StartService()
{
var baseAddress = new Uri("http://localhost:8080/RoomReservation");
host = new ServiceHost(
typeof(RoomReservationService));
}
var binding1 = new WSHttpBinding();
host.AddServiceEndpoint(typeof(IRoomService), binding1, baseAddress);
host.Open();
In addition to defining the binding programmatically, you can define it with the application configuration
file. The configuration for WCF is placed inside the element . The
element defines the services offered. Similarly, as you’ve seen in the code, the service needs an endpoint,
and the endpoint contains address, binding, and contract information. The default binding configuration of
wsHttpBinding is modified with the bindingConfiguration XML attribute that references the binding
configuration wsHttpConfig1. This is the binding configuration you can find inside the
section, which is used to change the wsHttpBinding configuration to enable reliableSession.
