3. Run (F5)
4. Alternatively run the Avalonia UI with:

   dotnet run --project UniversalCodePatcher.Avalonia

Usage

1. File → New Project (select project folder)
2. Check files to analyze in project tree
3. Project → Scan Files
4. Create patch rules in Rules tab
5. Apply patches with visual preview

Requirements

• .NET 6.0 or higher
• Windows OS
• Visual Studio 2022 (for development)

Avalonia Windows

Avalonia dialogs were audited to ensure buttons close their windows and inputs are connected. Debug output was added to verify each handler. Audited windows:

• BackupManagerWindow
• ModuleManagerWindow
• SettingsWindow
• FindWindow
• NewProjectWindow
• AboutWindow and simple dialogs (Confirm, Info, Error)

Some windows still use placeholder data and may need further binding to view models.
