101 How to on Windows Phone – How to #16 – Play with MarketPlace Review Task in Windows Phone

 

In this short tutorial we are going to see how to make use of MarketPlace Review Task, with this task we can get all the reviews of the application from which the task is triggered. Market Place Review task launches the Market Place client application and pulls the reviews for the application from which its launched, we need to login with the Windows Live ID to write a review. Let us see the steps on how to achieve this task in real time for a Windows phone application.      [more]

Open Visual Studio 2010 IDE and create a new Silverlight for Windows Phone project with a valid project name as shown in the screen below. Once the project is created add some controls which are used to trigger the MarketPlace review Task as shown in the screen below.

Now drag and drop few controls to the screen which is used to trigger event that launches the Market Place review Task. Once we designed the screen with the controls we can see the screen looks like below.

Now we need to write our code in the button click event to trigger the Market Place review task on the user click. To do that just go to the code behind and first add the USING handler code on top with the existing using statements as shown in the code below.

using Microsoft.Phone.Tasks;

Next is to add the below code to the button click event which basically creates an instance of the Market place review task as shown in the code below.

Code:

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 Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;

namespace F5debugHowto16
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            MarketplaceReviewTask mpReview = new MarketplaceReviewTask();
            mpReview.Show();
        }
    }
}

Now we are done with our code, just run the application by pressing F5 directly from the keyboard or we can use the Build and execute the project option from the tool bar to run the application. Once the Build is successful we can see the Windows Phone emulator with the application and the expected outputs as shown in the screens below.

Output Screens:

We can see an error shown by the market place, since we are using the Windows Phone Emulator to test the application we are getting this error since Windows Live ID is mandatory to login and write the review or to fetch the review. That’s it from this short tutorial on Windows Phone see you all in the next tutorial soon. Mean while Happy Programming!!!
