How can I handle the starting of a .Net MAUI App by MAC-Finder with a document? (open with..)

Question

In Mac-OS I can start a MAUI-App in Finder by selecting a file - and using „Open with“. If the App supports this document-type - how do I get the Filename/path to open in the implementation of the MAUI-App?

It seems not be delivered in the CommandLine-Args of the App.

Answer 1

Correct - the App shall be started by a selection of a file in Finder with :

(Select File) -> Right Mouse Click -> Open With -> MyApp....

My question was, how I can handle that in my .Net MAUI-App.

I meanwhile found the solution:

In MauiProgram.cs, I have to configure Lifecycle-Events:

        builder.ConfigureLifecycleEvents(events =>
		{
#if IOS || MACCATALYST
            events.AddiOS(ios => ios
						.OnActivated       ((app)          => App.OnActivated         ())
						.OnResignActivation((app)          => App.OnResignActivation  ())
						.DidEnterBackground((app)          => App.DidEnterBackground  ())
						.WillTerminate     ((app)          => App.WillTerminate       ())
						.FinishedLaunching ((app,par)      => App.FinishedLaunching   (par))
						.OpenUrl           ((app,url,opts) => App.OpenMidiFileWithUrl (url, opts))
				        );
#endif

        });
