step1.
Create one asp.net project like this
Step2:
Add WCF file like this
Step 3:
Add the operation contract
int Add(int a, int b);
in IService.cs file. as shown in Image
Step4
Go to Service.Cs file and click on “IService” as shown in Image
then Click on Explicitly Implement Interface.
then it will create interface add method.
Step 5: Write the code like this
int IService.Add(int a, int b)
{
return (a + b);
}
Step 6: For checking the service,click F5 you will get output like this
Step 7: Add Service Reference like this
Step 8:Click on Discover and Give the Namespace name like this
Step 9:Click on advance and Select “Generate Asyncronous Communication” like this
Step 10: Click ok. Then Come to “Default page” and keep there 2 textbox and one Button control like this
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”Default.aspx.cs” Inherits=”_Default” %>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head runat=”server”>
<title></title>
</head>
<body>
<form id=”form1″ runat=”server”>
<div>
<asp:TextBox ID=”TextBox1″ runat=”server”></asp:TextBox>
<asp:TextBox ID=”TextBox2″ runat=”server”></asp:TextBox>
<br />
<br />
<asp:Button ID=”Button1″ runat=”server” onclick=”Button1_Click” Text=”Button” />

Step 11. Click on” Button 1″ on write the following code in code behind for calling WCF service.
protected void Button1_Click(object sender, EventArgs e)
{
WcfTest.ServiceClient ws = new WcfTest.ServiceClient();
int result = ws.Add(int.Parse(TextBox1.Text), int.Parse(TextBox2.Text));
