Lock screen apps sample

This sample shows how an app can have a presence on the lock screen—the screen that is shown when the computer is locked—with a badge to provide basic status information or a tile to provide more detailed status. An app can also send toast notifications to the lock screen. All apps that are granted a lock screen presence also have the ability to perform background tasks.

The sample demonstrates the following scenarios:

  • Requesting lock screen access for the app
  • Querying for the current lock screen access status of the app
  • Removing the app's lock screen access at its request
  • Sending a badge update notification to an app's badge on the lock screen
  • Sending a text-only tile update notification to an app's tile on the lock screen
  • Using secondary tiles with the lock screen

The app that has a lock screen presence must declare one or more of the following types of background tasks:

  • Control channel
  • Timer
  • Push notification

In Microsoft Visual Studio 2013, this value is set in the Declarations page of the manifest editor, which sets the BackgroundTasks element in the package.appxmanifest file. This value has been set for this sample.

For an app to send a toast notification, the developer must have declared that the app is toast-capable in its app manifest file (package.appxmanifest) as has been done in this sample app. Normally, you do this by using the Visual Studio 2013 manifest editor, where you'll find the setting in the Application UI tab, under the Notifications section. For more info, see How to opt in for toast notifications.

Build the sample

  1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
  2. Start Microsoft Visual Studio 2015 and select File > Open > Project/Solution.
  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio 2015 Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

  • Select Build > Deploy Solution.

Deploying and running the sample

  • To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or select Debug > Start Without Debugging.
