Window in SilverLight 5 Via WCF Service

Introduction

Today, in this article let's concentrate on another SilverLight application, whereby communicating with a WCF Service to perform some operation.
 
Question: What is Window?
 
In simple terms SilverLight 5 applications enable us to create native windows which can run outside of the browser. Let's get this implemented practically for a better idea of this.

Step 1: The complete code of the 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_Window_SL

{

    // 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]

        double add(double a, double b);

 

        [OperationContract]

        double sub(double a, double b);

 

        [OperationContract]

        double mul(double a, double b);

 

        [OperationContract]

        double div(double a, double b);

    }

}

 

Step 2: The complete code of the Service1.svc.cs looks like this.

 

using System.ServiceModel.Web;

using System.Text;

 

namespace WCF_Window_SL

{

    // 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 double add(double a, double b)

        {

            return a + b;

        }

        public double sub(double a, double b)

        {

            return a - b;

        }

        public double mul(double a, double b)

        {

            return a * b;

        }

        public double div(double a, double b)

        {

            return a / b;

        }

    }

}

 

Step 3: The complete code of the 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 the Clientaccesspolicy.xml looks like this (to avoid cross domain problem in SilverLight).

 

<?xml version="1.0" encoding="utf-8"?>

<access-policy>

  <cross-domain-access>

    <policy>

      <allow-from http-request-headers="SOAPAction">

        <domain uri="*"/>

      </allow-from>

      <grant-to>

        <resource path="/" include-subpaths="true"/>

      </grant-to>

    </policy>

  </cross-domain-access>

</access-policy>

 

Step 5: The complete code of the ArthmeticWindow.xaml (UserControl) looks like this.

<UserControl x:Class="Silverlight_Window_Application.MainPage"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                FontSize="22"

                Height="67"

                HorizontalAlignment="Right"

                Margin="0,108,89,0"

                Background="DeepSkyBlue"

                Click="button1_Click"

                Typography.StylisticSet7="True"/>

    </Grid>

</UserControl>

 

Step 8: The complete code of the 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;

 

namespace Silverlight_Window_Application

{

    public partial class MainPage : UserControl

    {

        public MainPage()

        {

            InitializeComponent();

        }

 

        private void button1_Click(object sender, RoutedEventArgs e)

        {

            Window obj_Window = new Window();

            obj_Window.Width = 500;

            obj_Window.Height = 350;

            obj_Window.Title = "Arthimetic New Window SL 5 via WCF";

            obj_Window.Content = new ArthmeticWindow();

            obj_Window.Visibility = System.Windows.Visibility.Visible;

        }

 

    }

}

 

Step 9: Before you rebuild and run the application.

 

Go To Properties of SilverLight Application.

 

Select the CheckBox, Enable running application out of browser.

 

Then, click on Out of Browser Setting - Button.

 

Select the CheckBox, Require Elevated trust when running the application outside of the browser.

 

Step 10: The output of the application looks like this.

 

Step 11: The output of the Arithmetic Window Application looks like this.

 

Step 12: The output of the Nothing Entered Application looks like this.

Step 13: The output of the Addition Operation Application looks like this.
