This sample shows you how to launch an app for to handle a file type or a protocol (also known as custom scheme). You can also learn how to enable your app to be the handler for a file type or a protocol.
Note This sample was created using one of the universal app templates available in Visual Studio. For more info about how to build apps that target Windows 10 with Visual Studio, see Build a Windows 10 universal app using Visual Studio.
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
- 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.
To obtain an insider copy of Windows 10, go to Windows 10.
Note For Windows 10 app samples, go to Windows 10 Samples. The samples for Windows 10 can be built and run using Windows developer tools.
