An app without services is a really broken app and noting will actually launch.

In fact, this error is really weird because:

var mauiApp = CreateMauiApp();
var rootContext = new MauiContext(mauiApp.Services, this);
var applicationContext = rootContext.MakeApplicationScope(this);

_services = applicationContext.Services;

The CreateMauiApp should always create a new services instance. This is where you are registering your app services.

However, if you look at the exception, you can see the real issue is coming from Compatibility:

Are you using anything from compatibility?

But, this still gets more weird. The constructor of MauiApplication is setting IPlatformApplication.Current = this and by the time this event is fired, the services are set so IPlatformApplication.Current.Services should not be null.

I am going to add some more comments to the linked issue for duscussion and see if we can figure out some repro and/or info on the scenarios that cause this to happen - it seems impossible.

Are you using anything from compatibility?

Yeah, we have .UseMauiCompatibility(). So, in theory if we migrate all the left over renderers we have and remove this line everything should be ok?

Yeah, you might be able to use renders still, if you manually register them.

@PureWeen do we have docs on how to migrate the old renderers to the rendlers or handerers (the renderer-looking handlers).
