Launching App Market Page From App In Windows Phone 8


This article explains the Marketplace Detail Task and how to open the Marketplace Application page from your app. This task helps to launch the App Store from our app for a specific app. It can be very useful for advertising our apps.

Marketplace Detail Task

This is a kind of launcher provided by Windows Phone to launch the Windows Phone marketplace. This task expects two parameters to be set and on the basis of those parameters users can launch the marketplace app from the app itself. 

Before using this task we need to include the following namespace:

using Microsoft.Phone.Tasks;

This task has the following properties that we can use:

  • Content Identifier
    Sets the unique identifier for the product to be displayed.
  • Content Type
    Sets the type of the content displayed in the store client application.

To use this task we need to set the preceding two properties properly.


Let's see how to use it in a contact us page of our app. Here our app page will help the user to drive to our office from their location.
