How to Save an EMail Address in Windows Phone 7 Via WCF Service

Today, in this article let's play around by implementing one of the interesting concepts often used on a day-to-day basis in Windows Phone.
So, let's get it started 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 Save_Email_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 Email(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 Save_Email_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 Email(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>
              <!-- To avoid disclosing metadata information, set the value below to false and

remove the metadata endpoint above before deployment ->                                                                                                   <serviceMetadata httpGetEnabled="true"/>

                  <!-- To receive exception details in faults for debugging purposes, set the value below to true.

  Set to false before deployment to avoid disclosing exception information -->

                    <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:

            </shell:ApplicationBar.MenuItems>
        </shell:ApplicationBar>
    </phone:PhoneApplicationPage.ApplicationBar>-->

</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.Controls;
using Save_Email_App.ServiceReference1;
using Microsoft.Phone.Tasks;

namespace Save_Email_App
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (textBox1.Text == "")
            {
                textBlock2.Text = "Please Enter Email";
                textBlock2.Foreground = new SolidColorBrush(Colors.Red);
            }
            else
            {
                Service1Client objClient = new Service1Client();
                objClient.EmailCompleted += new EventHandler<EmailCompletedEventArgs>(EmailCall);
                objClient.EmailAsync(textBox1.Text); 
            }
        }

        static void EmailCall(object sender, EmailCompletedEventArgs e)
       {
            SaveEmailAddressTask objEmailTask = new SaveEmailAddressTask();
            objEmailTask.Email = e.Result;
            objEmailTask.Show();
        }
    }
}

The Output of the Application looks like this:
