Introduction

This concept allows the phone user to handle the task easily in a lightweight manner.

Question Arises: What is Application Bar?

An Application Bar is similar to the taskbar in our desktop computer systems. We will add a list of applications to our tray and it will be easy to operate some phone functionalities. It provides a good UI overriding the cluttered environment. Once we implement this concept we will get a better grip on this.

So, let's get it started!!!

The Complete Code of IService1.cs looks like this.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WCF_Application_Bar
{
    // 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);
        [OperationContract]
        double Mul(double a, double b);
        [OperationContract]
        double Div(double a, double b);
        [OperationContract]
        string Menu();
    }
}

The Complete Code of Service1.svc.cs looks like this.

Code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;
namespace WCF_Application_Bar

{
// 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 double Add(double a, double b)

{

return a + b;

}
public double Sub(double a, double b)

{

return a - b;

}
public double Mul(double a, double b)

{

return a * b;

}
public double Div(double a, double b)

{

return a / b;

}
public string Menu()

{

return "Hurray!!!...I am from WCF for Menu Item";

}
}
}

The Complete Code of Web.Config looks like this.

Code:

<?xml version="1.0"?>
<configuration>
<system.web>
    <compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          
          <serviceMetadata httpGetEnabled="true"/>
          
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>

The Complete Code of MainPage.xaml looks like this.

Code:
