Constructor - Binding + Endpoint

1. BasicHttpBinding için 
Şöyle yaparız.

BasicHttpBinding binding = new BasicHttpBinding();
EndpointAddress address = new EndpointAddress("http://localhost/Service1.svc");
var channelfactory = new ChannelFactory<IService1>(binding, address);

Eğer istersek binding için daha fazla parametre verebiliriz.

EndpointAddress endpoint = new EndpointAddress(@"http://localhost/Service1.svc");

BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
basicHttpBinding.MaxReceivedMessageSize = int.MaxValue;
basicHttpBinding.Security.Transport.ClientCredentialType = 
HttpClientCredentialType.Basic;
basicHttpBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;

var channelFactory = new ChannelFactory<IService1>(basicHttpBinding, endpoint);

2. NetNamedPipeBinding
Şöyle yaparız.

var channelfactory = new ChannelFactory<IMyService>(
    new NetNamedPipeBinding(), new EndpointAddress(hostUrl));

Credentials alanı

Şöyle yaparız.

channelFactory.Credentials.UserName.UserName = ... ;
channelFactory.Credentials.UserName.Password = ...

CreateChannel metodu

Şöyle yaparız.

var client = channelFactory.CreateChannel();
