WCF Error.Could not create and understand endpoint.What is host endpoints

Hi All,

I have recently started to study WCF and I am really confused in Endpoints.
What are Host endpoints exactly.

I have created a simple host and client service and hosted then in Windows Form.But i am unable to invoke services. :(
------------------------------------------------------------------------------------
Code of hostService-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService2
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {

        [OperationContract(IsOneWay=true)]
        void SendCreditLimitRequest(string id);


    }

}

and

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace WcfService2
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    public class Service1 : IService1
    {

        public void  SendCreditLimitRequest(string id)
        {
            double value;

            if (id == "1")
                value = 10;
            else if (id == "2")
                value = 20;
            else
                value = 0;


        }
    }
}

Code of my Window host is as :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.ServiceModel;
using System.ServiceProcess;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace host
{
    public partial class Form1 : Form
    {
        ServiceHost host;
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            host = new ServiceHost(typeof(WcfService2.Service1Client));
            host.Open();
            MessageBox.Show("Service Started!");

        }

        private void button2_Click(object sender, EventArgs e)
        {
            host.Close();
        }
    }
}

--------------------------------------------------------------------------------
and exception i am facing is---

System.InvalidOperationException was unhandled
  Message=Service 'host.WcfService2.Service1Client' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element.
