This video is so satisfying... I find "Patternization" of concepts such as this to be extremely insightful! Thank you for this video, keep it up!

Love the video, but I do wish it started more generally:
1. At a high level: How many ways are there to write platform specific code in Maui? If/else, partial classes, shared interfaces, etc?
2. When should I reach for compiler directives, partial classes, partial methods, shared interfaces or dependency injection? What are the use cases, advantages of each?
3. Would love to see an example of each!
Thanks again - extremely helpful!

During this video I was thinking that I would prefer doing it with dependency injection and having a shared Interface. Looks like I predicted your next video :D When is it going to be available?

Hello Gerald, could you make a video about splash screen with dark and light mode on each plataform please? :)

Hello Gerald. How does your example work in a .NET MAUI Class Library project?

Is it possible to access the underlying Android API, so you can access features for which .NET did not build an abstraction? I want to use the Picture-in-Picture mode in Android, but I don't think you can do that yet with the .NET Maui interface. Would it be possible to use the Picture-in-Picture mode in a .NET Maui project written in Java?

VS2022 17.2 Preview 1 doesn't seem to like UIKit. Is that no longer needed or in something else now?

Hello, Dependency injection not work for me, for some reason MAUI no detects the folder Platforms. But this method works. Thx,

Hello Gerald, do you know if there is any documentation on how to set the XAML according to platform ? I didn't find anything. I'm looking for somthing like "MyPage.android.xaml / MyPage.ios.xaml" because if you have a really different UI for each platform, it's not possible to rely on On<Android> everytime and everywhere otherwise it becomes unreadable and unmaintainable. Thanks!
