Initial v0.1 (commit df9dac0) used PhotinoNET wrapping WebView2 + HTML/JS,
but rendered as a blank window on first run — WebView2 + file:// URI
quirks. Switching to native WPF: built into the .NET 9 Windows SDK
(no NuGet), single-file self-contained publish, instant window open.
All Backend/*.cs orchestration logic carried over unchanged (they're
UI-framework-agnostic). Replaced:
- Program.cs (PhotinoNET bootstrap) -> App.xaml(.cs) + MainWindow.xaml(.cs)
- ui/index.html + style.css + app.js -> MainWindow.xaml (XAML views) +
App.xaml resource styles
- Backend/MessageBridge.cs (JS<->C# router) -> direct method calls in
MainWindow.xaml.cs code-behind
RecRoomPicker now uses Microsoft.Win32.OpenFolderDialog (added in .NET 8)
instead of WinForms FolderBrowserDialog — keeps the project WPF-only.
Backend files needed explicit 'using System.IO;' since the WPF SDK
doesn't include it in implicit usings.
