Introduction

Today, in this article let's learn another new and interesting concept related to Windows Phone 7, whereby communicating with WCF Service to perform some operation.

The Telerik Rad Controls for Windows Phone 7 can be downloaded from http://www.telerik.com/products/windows-phone.aspx.

The Rad Message Box is used to display the output in a nice and enhanced UI.

Question: What is a Dock Panel?

In simple terms "It provides flexibility for the user in accessing application, where elements are well aligned with Rich UI based in Dock. The elements in the dock panel are arranged according to the user requirement level. For instance: Left or Right or Top or Bottom".

Let's get this implemented 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_Dock_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
 {

[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;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WCF_Dock_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 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 MainPage.xaml looks like this:
 
<phone:PhoneApplicationPage
