Hi Team,

Could you please guide me how to redirect to the same instance of the Winui3 app(which will be already running) when i try to open the another instance of the same app...

Basically i need to immediately redirect to the currently running app(should activate and come to the front) when i open the another instance of the same app.

Best Regards,

    Welcome to Microsoft Q&A!

    In order to handle reactivation, the app can register for an Activated event. The event passes a Microsoft.Windows.AppLifecycle.AppActivationArguments instance to the app, which contains one of the -ActivatedEventArgs instances.

    When a registered activation is triggered, an instance of AppActivationArguments Class is passed to the event handler for the Activated event of the AppInstance class.

    For more details, I suggest you could refer to the Doc:App instancing with the app lifecycle API.

    You could refer to the sample: Handling activations.

    Thank you.
