Simplified Config File in WCF 4.5

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"?>

<system.serviceModel>

</basicHttpBinding>

</bindings>

</client>

</system.serviceModel>

<system.web>

</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>

</head>

<body>

<div>

<table>

<tr>

<asp:Label ID="Label1" runat="server" Text="Arthmetic Operations - WCF 4.5 Simplified Configuration"

Font-Bold="true" Font-Size="Large" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label3" runat="server" Text="Please Enter First Number" Font-Size="Large"

Font-Names="Verdana" Font-Italic="true"></asp:Label>

</td>

<td>

<asp:TextBox ID="TextBox2" runat="server" Width="120px"></asp:TextBox>

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label2" runat="server" Text="Please Enter Second Number" Font-Size="Large"

Font-Names="Verdana" Font-Italic="true"></asp:Label>

</td>

<td>

<asp:TextBox ID="TextBox1" runat="server" Width="120px"></asp:TextBox>

</td>

</tr>

<tr>

<asp:Button ID="Button1" runat="server" Text="Addition" Font-Names="Verdana" Width="213px"

BackColor="Orange" Font-Bold="True" OnClick="Button1_Click" />

</td>

</tr>

<tr>

<asp:Button ID="Button2" runat="server" Text="Substraction" Font-Names="Verdana"

Width="213px" BackColor="Orange" Font-Bold="True" OnClick="Button2_Click" />

</td>

</tr>

<tr>

<asp:Label ID="Label5" runat="server" Font-Bold="true" Font-Names="Verdana" ForeColor="Maroon"></asp:Label>

</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:
