About Prompt in Windows Phone 7 via WCF Service

Introduction

Firstly before we get to start working with Toast prompt, We need to download Coding4Fun Toolkit from http://coding4fun.codeplex.com/. Later add Coding4Fun.Phone.Controls.dll as a reference for our newly created project.

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

Question: What is About Prompt?

In Simple Terms "It is used to display some message or notification to the user and enables user to accept the notification stating that user has been through the notification. So this type of prompt enables to intimate the user with some concise information".

Let's get this started off now!!!

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 WCF_About_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 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_About_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 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>

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