Media Player in Windows Phone 7 via WCF Service

Introduction 

Today, in this article let' learn another concept in windows phone whereby interacting with WCF Service to receive some message. I think we all are now good to go and implement this concept.

Question Arises: What is Media Player Launcher?

In Simple Terms "It performs simple media tasks launching player. It plays outs requested media files from directory or isolated storage device."

So, let's get it started off!!!

Step 1: 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 Media_Launcher_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 Media();

    }
}

Step 2: 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 Media_Launcher_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 Media()
        {
            return " Whoomp!!!Message from WCF for Media Launcher ";
        }
    }
}

Step 3: 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>

Step 4: The Complete Code of MainPage.xaml looks like this:

<phone:PhoneApplicationPage
    x:Class="Media_Player_Launcher_Application.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait" Orientation="Portrait"
    shell:SystemTray.IsVisible="True">
 
    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
 
        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="Vijay's Media Player Application" FontFamily="Verdana" FontSize="22" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="Windows 7 Phone" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <Button Content="Button" FontFamily="Verdana" FontSize="22" Height="72" HorizontalAlignment="Left" Margin="160,67,0,0" Name="button1" VerticalAlignment="Top" Width="160" Click="button1_Click" />
        </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 1"/>
                <shell:ApplicationBarMenuItem Text="MenuItem 2"/>
            </shell:ApplicationBar.MenuItems>
        </shell:ApplicationBar>
    </phone:PhoneApplicationPage.ApplicationBar>-->

</phone:PhoneApplicationPage>

Step 5: 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 Media_Player_Launcher_Application.ServiceReference1;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;

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

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            Service1Client objClient = new Service1Client();
            objClient.MediaCompleted += new EventHandler<MediaCompletedEventArgs>(media_Call);
            objClient.MediaAsync();
        }

        static void media_Call(object sender, MediaCompletedEventArgs e)
        {

            MediaPlayerLauncher objMedia_Player = new MediaPlayerLauncher();
            objMedia_Player.Media = new Uri("http://video.ch9.ms/ch9/6e44/55f3a9d2-879c-4c92-919e-9fd500126e44/iwp30atux_med_ch9.mp4", UriKind.Absolute);
            objMedia_Player.Location = MediaLocationType.Data;
            objMedia_Player.Controls = MediaPlaybackControls.All;
            objMedia_Player.Orientation = MediaPlayerOrientation.Portrait;
            MessageBox.Show(e.Result);
            objMedia_Player.Show();
        }
    }
}

Step 6: The Output of the Application looks like this:

Step 7: The WCF Service Message Output Application looks like this:
