The Avalonia UI code (App, Views, ViewModels, Localization, Assets) now lives in src/App as a plain library (no OutputType). Two thin heads reference it: - src/App.Desktop/ — WinExe, Avalonia.Desktop, hosts MainView in a MainWindow; carries Program.cs and app.manifest (moved from src/App) - src/App.Android/ — net10.0-android, Avalonia.Android, MainActivity/ MainApplication; targets API 23+, EmbedAssembliesIntoApk=true so the apk is self-contained for sideloading All event handlers and TopLevel-dependent calls (file picker, clipboard, folder picker) moved from MainWindow.axaml.cs into the new shared MainView.axaml.cs (UserControl), using TopLevel.GetTopLevel(this) so they work on both platforms. Esc/Back key handling is also in MainView. MainWindow becomes a thin shell that hosts MainView. Framework bump: all projects move to net10.0; Cli and Tests follow.
