Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.
This sample covers these key tasks:
- launching an app for a file using LaunchFileAsync
- handling file activation through the Activated event
- launching an app for a protocol using LaunchUriAsync
- handling protocol activation through the Activated event
- associating the app with a website using the AppUriHandler extension
- launching a target app and having the currently running source app remain on the screen for various amounts of screen space using LauncherOptions.DesiredRemainingView.
- Note LauncherOptions.DesiredRemainingView is only supported on desktop Windows when it is running in tablet mode.
