Today, in this article let's play around by implementing an interesting concept often used on a day-to-day basis in Windows Phone. This concept is highly useful for people who become involved with sharing messages across social networking sites. This article clearly demonstrates necessary information conveying to the reader actual illustrations and work with real-time scenarios that they come across when asked to use ShareStatusTask.

So, let's get it started off now.

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 Share_Status_App_WCF
{
    // 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]
        string Status(string a);
    }
}

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 Share_Status_App_WCF
{
    // 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 string Status(string a)
        {
            return "" + a;
        }
    }
}

The Complete Code of Web.Config looks like this:

<?xml version="1.0"?>
<configuration>
     <system.web>
        <compilation debug="true" targetFramework="4.0" />
    </system.web>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior>

The Complete Code of MainPage.xaml looks like this:

        </Grid>
    </Grid>

</phone:PhoneApplicationPage>

The Complete Code of MainPage.xaml.cs looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

using Microsoft.Phone.Shell;
using ShareStatus_Task.ServiceReference1;

namespace ShareStatus_Task
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }
        PhoneApplicationService objPhone = PhoneApplicationService.Current;
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (textBox1.Text == "")
            {
                textBlock2.Text = "Please Enter Status";
                textBlock2.Foreground = new SolidColorBrush(Colors.Red);
            }
            else
            {
                Service1Client objClient = new Service1Client();
                objClient.StatusCompleted += new EventHandler<StatusCompletedEventArgs>(StatusCall);
                objClient.StatusAsync(textBox1.Text);
             }
        }

        static void StatusCall(object sender, StatusCompletedEventArgs e)
        {
            ShareStatusTask objTask = new ShareStatusTask();
            objTask.Status = e.Result;
            objTask.Show();
        }

        protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            object sample;
            if (objPhone.State.TryGetValue("statusp", out sample))
                textBox1.Text = sample as string;
            base.OnNavigatedTo(e);
        }

        protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e)
        {
            objPhone.State["statusp"] = textBox1.Text;
            base.OnNavigatedFrom(e);
        }
    }
}

The Output of the Application looks like this:
