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>
          
          <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:

            <TextBlock x:Name="PageTitle" Text="Windows 7 Phone" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>

        {

            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 = "";
            }
        }
