Making Phone Call with WCF Service Hosted on Windows Phone 7


Today, in this article let's see one of the interesting concept of how to make a call using Windows Phone 7 with WCF Service.

So, I think we all are good to go and implement this wonderful concept.

Let's get it started off!!!

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 WCF_WP7_Call_Application
{
    // 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
    {
        #region WCF Operational Contracts

        [OperationContract]
        string Name(string a);

        [OperationContract]
        int Number(int a);

        #endregion

    }
}

The Complete Code of Service1.svc 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 WCF_WP7_Call_Application
{
    // 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 Name(string a)
        {
            return a;
        }

        public int Number(int 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:

        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">

            <TextBox Margin="123,106,113,430" HorizontalAlignment="Center" Width="220" FontFamily="Verdana" FontSize="22" Name="textbox1" />

        </Grid>
    </Grid>

    <!--Sample code showing usage of ApplicationBar-->
    <!--<phone:PhoneApplicationPage.ApplicationBar>
        <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
            <shell:ApplicationBarIconButton IconUri="/Images/appbar_button1.png" Text="Button 1"/>
            <shell:ApplicationBarIconButton IconUri="/Images/appbar_button2.png" Text="Button 2"/>
            <shell:ApplicationBar.MenuItems>

                <shell:ApplicationBarMenuItem Text="MenuItem 2"/>
            </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 Windows_Phone_Call_Task.ServiceReference1;
using Microsoft.Phone.Tasks;

namespace Windows_Phone_Call_Task
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }
        static void NameCall(object sender, NameCompletedEventArgs e)
        {
            PhoneCallTask objDisplayName = new PhoneCallTask();
            objDisplayName.DisplayName = e.Result + " via WCF Service";
            objDisplayName.Show();
        }
        static void NumberCall(object sender, NumberCompletedEventArgs e)
        {
            PhoneCallTask objNumberTask = new PhoneCallTask();
            objNumberTask.PhoneNumber = e.Result.ToString() + " via WCF Service";
            objNumberTask.Show();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {

            if (textbox1.Text == "" || textBox2.Text == "")
            {
                textBlock3.Text = "Please Enter Some Values";
                textBlock3.Visibility = Visibility.Visible;
            }
            else
            {
                Service1Client objClient = new Service1Client();
                objClient.NameCompleted += new EventHandler<NameCompletedEventArgs>(NameCall);
                objClient.NameAsync(textbox1.Text);
                objClient.NumberCompleted += new EventHandler<NumberCompletedEventArgs>(NumberCall);
                objClient.NumberAsync(Convert.ToInt32(textBox2.Text));
                textbox1.Text = "";
                textBox2.Text = "";
            }
        }

    }
}

The Output of Application looks like this:

Phone0.png

The Output of Application after Call Button click looks like this:

Phone1.png

The Output of the Application Calling Number looks like this:

  Phone2.png
