Introduction
Today, in this article let's play around with one of the interesting and most useful concepts in WCF 4.5.
Question: What is simplified configuration?
In simple terms "It enables the config file to reduce the complexity and maximizes the usage power. Adding a service reference only generates the necessary config".
Step 1: Create a new WCF 4.5 project.

Step 2: The complete code of IService1.cs looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService1
{
// 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]double Add(double a, double b);
[OperationContract]double Sub(double a, double b);
}
}
Step 3: The complete code of Service1.svc.cs looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService1
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
// NOTE: In order to launch WCF Test Client for testing this service, please select Service1.svc or Service1.svc.cs at the Solution Explorer and start debugging.
public class Service1 : IService1{public double Add(double a, double b)
{
return a + b;
}
public double Sub(double a, double b)
{
return a - b;
}
}
}
Step 4: The complete code of web.config file looks like this (Simplified Configuration):
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IService1"/>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:7395/Service1.svc" binding="basicHttpBinding" contract="WCFApp.IService1" bindingConfiguration="BasicHttpBinding_IService1" name="BasicHttpBinding_IService1"/>
</client>
</system.serviceModel>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Step 5: Create a new webforms project and add the service reference of the new WCF project; see:

Step 6: The complete code of WebForm1.aspx looks like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="SimplifiedConfigurationApp.WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<title></title>
</head>
<body>
<form id="form1" runat="server">
<center>
<div>
<table>
<tr>
<td colspan="2">

</td>
</tr>
</table>
</div>
</center>
</form>
</body>
</html>
Step 7: The complete code of WebForm1.aspx.cs looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using SimplifiedConfigurationApp.ServiceReference1;namespace SimplifiedConfigurationApp
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
TextBox2.Focus();
}
protected void Button1_Click(object sender, EventArgs e)
{
double val1 = double.Parse(TextBox2.Text);
double val2 = double.Parse(TextBox1.Text);
if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))
{
Label5.Text = "Please Enter Some Values";
Label5.ForeColor = System.Drawing.Color.Red;
}
else
{
Label5.Text = "The Addition of " + TextBox1.Text + " and " + TextBox2.Text + " is " + objClient.Add(val1, val2);
Label5.ForeColor = System.Drawing.Color.Green;TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
}
}
protected void Button2_Click(object sender, EventArgs e)
{
double val1 = double.Parse(TextBox2.Text);
double val2 = double.Parse(TextBox1.Text);
if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))
{
Label5.Text = "Please Enter Some Values";
Label5.ForeColor = System.Drawing.Color.Red;
}
else
{
Label5.Text = "The Substraction of " + TextBox1.Text + " and " + TextBox2.Text + " is " + objClient.Sub(val1, val2);
Label5.ForeColor = System.Drawing.Color.Green;
TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
}
}
#regionService1Client objClient = new Service1Client();
#endregion}
}
Step 8: The output of application looks like this:

Step 9: The addition operation output of the application looks like this:
