Windows 10 requirements

Remarks

This class and the rest of the Windows.Services.Store namespace was introduced in Windows 10, version 1607. This class can only be used in projects that target Windows 10 Anniversary Edition (10.0; Build 14393) or a later release in Visual Studio. If your project targets an earlier version of Windows 10, you must use the Windows.ApplicationModel.Store namespace instead of the Windows.Services.Store namespace. For more information, see In-app purchases and trials.

The StoreContext class is the main entry point to the Windows.Services.Store namespace. Use members of this class to perform tasks such as getting Microsoft Store listing and license info for the current app, purchasing the current app or add-ons that are offered by the app, or downloading and installing package updates for the app. Other classes and types in this namespace represent items such as add-ons for the app, licenses for the app and its add-ons, and Microsoft Store listing info for the app.

To get a StoreContext object, use one of these static methods:

GetDefault: Use this method in single-user apps (that is, apps that run only in the context of the user that launched the app). This method gets a StoreContext object that you can use to access and manage Microsoft Store-related data for the user. Most Universal Windows Platform (UWP) apps are single-user apps.

GetForUser: Use this method in multi-user apps. This method gets a StoreContext object that you can use to access and manage Microsoft Store-related data for a specific user. For more information about multi-user apps, see Introduction to multi-user applications.

In a Windows desktop application that uses the Desktop Bridge, you must add some additional code to configure the StoreContext object before your app can use this object. For more information, see Using the StoreContext class in a desktop application that uses the Desktop Bridge.

After you have a StoreContext object, you can start calling methods to purchase an app or add-on for the current user and other tasks. For more information, see the following articles:

You can also use a StoreContext object to download and install package updates for the app. For more information, see Download and install package updates for your app.
