Summary

Conclusions

.NET MAUI lets you create applications for Android, iOS, macOS, and Windows from one project in C# and XAML: handlers convert cross-platform elements into native ones, and the shared code runs on .NET 10. Development is convenient on the Windows Machine target, and testing in an Android emulator with hardware virtualization or on your own phone. Pages are built from layout containers, styles, and themes, data is shown through compiled x:DataType bindings and CollectionView, and logic is moved into ViewModels with CommunityToolkit.Mvvm that receive services through the DI container in MauiProgram. Shell describes tabs and routes and passes parameters between pages. Device services (Preferences, Geolocation, MediaPicker, sensors) require checking for support, permissions, and work with the main thread, and data is stored in files or SQLite or obtained from web services.
