Introduction:
In this article,i am going to explain about how to access a wcf service with adding the service reference.

Main:
We can easily perform this task using channel factory.A channelfactory is a class that helps us to
creates channels of different types that are used by clients to send messages to variously configured
service endpoints.

Demonstration:

1.make a wcf service is hosted and running,

2.Declare the same interface in client side,

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.ServiceModel;
using System.ServiceModel.Channels;
 
using NetTcpLibarary;
 
namespace NetTcpClient
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        [ServiceContract]
        interface INetTcpService
        {
            [OperationContract()]
            DataSet ReturnEmpDetails(int EmpId);            
        }
 
 
        private void Form1_Load(object sender, EventArgs e)
        {
 
            NetTcpBinding basicHttpBinding = new NetTcpBinding();
            EndpointAddress endpointAddress = new EndpointAddress
              ("net.tcp://localhost:8000/TcpBinding");
 
            IChannelFactory<INetTcpService> channelFactory =
new ChannelFactory<INetTcpService>(basicHttpBinding);
 
 
           // IChannelFactory<INetTcpService> local_channelfactory =
             //    new IChannelFactory<INetTcpService>(basicHttpBinding);
 
            INetTcpService proxy = channelFactory.CreateChannel(endpointAddress);
 
            DataSet local_ds = proxy.ReturnEmpDetails(5303);
 
            if (local_ds.Tables[0].Rows.Count > 0)
            {
                MessageBox.Show(local_ds.Tables[0].Rows[0].ItemArray[0].ToString());
 
            }
 
            //dataGridView1.DataSource = local_ds;
           // dataGridView1.DataBindings();         
 
 
        }
    }
}
