RANDOM MAC v1.1.1

UX polish + correctness fixes on top of the WinUI 3 framework migration that landed in v1.1.0. Application logic in RandomMac.Core is unchanged. Existing settings.json / blacklist.json / history.json files load without migration.

Built with C# 13 / .NET 11 (preview) for the App project, .NET 9 for Core.

Highlights

  • Tray quick action — right-click the tray icon → "Randomize Active Adapter" applies a fresh MAC to the first connected adapter without opening the window.
  • Hamburger toggle — collapse the navigation pane to icon-only (48px).
  • Auto-apply Settings — every toggle / combo applies immediately and persists with a 500ms debounce. The "Save" button is gone.
  • Window 1024×680 — was 880×600. More breathing room for the DataGrid history and the Settings sections.
  • Auto-update check on launch — silent, throttled to once every 24h. Surfaces a toast if a new version is available.
  • History retention — entries older than 30 days are pruned automatically; saves are atomic via .tmp+File.Move; corrupt files are backed up to .bak.<ts> before any new write.
  • Bundle export — Settings → "Export All (zip)" produces a single ZIP with settings.json + blacklist.json + history.json for backup or migrating between machines.
  • History filter — live search above the Recent History grid by adapter name or MAC string.
  • Keyboard shortcuts — Ctrl+1..5 to jump pages, Ctrl+R Randomize, Ctrl+Enter Apply.
  • Empty state + status InfoBars — Dashboard shows a "Pick an adapter" hint when nothing is selected; status messages appear in an InfoBar that auto-clears after 5 seconds.
  • Polish — page transitions (slide+fade), Update view rewrite (state-driven hero card with last-checked), About rewrite (centered hero + compact dependency list), connection icon + text (was a 10px dot), WiFi/Ethernet glyphs in the adapter dropdown, relative timestamps in history ("just now" / "5 min ago" / "yesterday" / yyyy-MM-dd HH:mm), Mica + Acrylic backdrop fallback chain, scrollbars hidden but scroll input still works.

Bug fixes

  • DataGrid headers in Recent History showed the literal string Microsoft.UI.Xaml.Data.Binding. DataGridColumn is not in the visual tree, so XAML {Binding} on Header doesn't resolve. Headers are now set from DashboardView.xaml.cs and refreshed on Loc.PropertyChanged.
  • Dashboard Refresh always reported "Error loading adapters". IAdapterCacheService.RefreshAsync uses ConfigureAwait(false), so subscribers ran on the threadpool and mutated the bound ObservableCollection cross-thread. Subscribers now marshal through App.MainDispatcher.TryEnqueue.
  • Recent History timestamps always read "7 h ago" on UTC+7 machines. Timestamp defaults to DateTime.UtcNow (correct), but the converter computed DateTime.Now - when (local - utc). Fixed by normalizing the input via Kind-aware ToLocalTime().
  • Recent History wiped when in-memory list happened to be empty. LoadAsync used to swallow JSON parse failures; the next SaveAsync then wrote the empty list, overwriting the user's on-disk entries. Hardened with a _loadCompleted gate, corrupt-file backup, and atomic .tmp+File.Move writes.
  • FontIcon glyphs invisible — raw Private-Use-Area chars in XAML attribute values were silently stripped to empty by the file write pipeline. Replaced all inline glyphs with XML entity references (&#xE72C;).
  • Hamburger collapse left "first letter peek" — custom MenuItemTemplate rendered the label TextBlock independently of the auto-collapse logic. Added IsPaneOpen two-way binding on MainWindowViewModel and a NavItem.Owner back-reference so the template can hide the label.
  • Tray right-click menu items inert + double-click no-op + window not focused on Show. Added XamlRoot lazy-init for MenuFlyout, DoubleClickCommand, and Win32 ShowWindow(SW_RESTORE) + SetForegroundWindow.
  • LogView "Failed to export log: File extensions must begin with '.' and contain no wildcards". WinUI 3 FileSavePicker.FileTypeChoices rejects .*. Removed the wildcard entry.
  • Settings export / import / bundle export consistently failed in elevated unpackaged WinUI 3. Windows.Storage.Pickers.FileSavePicker/FileOpenPicker route through a broker that can't elevate cross-process. All four pickers (Settings export, Settings import, Bundle export, Log export) now use a Win32 comdlg32 wrapper (Helpers/Win32FileDialog.cs) running in-process. Output buffer uses IntPtr instead of StringBuilder so the OPENFILENAMEW struct is blittable for Marshal.SizeOf.
  • Resources["Loc"] = Loc.Instance crashed at startup with COMException 0x8000FFFF. The COM proxy isn't fully wired in the App constructor even after InitializeComponent(). Moved to the start of OnLaunched.
  • Plain dotnet build failed with WindowsAppSDKSelfContained requires a supported Windows architecture. Added a default RuntimeIdentifier=win-x64 in the csproj so Rider/VS builds work without -r flags.

Removed

  • The 6-color accent picker. Brand accent is hardcoded to #61AFEF. The AccentColor field is dropped from AppSettings; existing settings.json files load without migration (System.Text.Json ignores unknown keys).
  • The "Save" button from Settings (everything auto-applies + auto-saves now).
  • The "All Files (.*)" choice from LogView's export dialog (WinUI 3 picker rejects wildcards).
  • Dead accentColor parameter from ThemeService.Apply(string mode, string accentColor) → now Apply(string mode).

What did NOT change

  • Every algorithm in RandomMac.Core: MAC generation, registry write, WMI restart, blacklist, history, settings, OUI lookup, update service.
  • Velopack 0.0.1298 packaging (unpackaged, self-contained).
  • requireAdministrator manifest (no UAC at boot via Task Scheduler).
  • All 116 localization keys in Lang.resx / Lang.vi.resx.
  • All 37 RandomMac.Tests unit tests still pass.

Smoke checklist (manual)

  1. Launch as Administrator. Window opens at 1024×680, fixed, no maximize.
  2. Toggle theme Dark↔Light and language EN↔VI in Settings — UI re-renders live, no Save click needed.
  3. Press Ctrl+1..5 from anywhere — jumps to corresponding nav page.
  4. Minimize → tray icon visible. Double-click → window restored to foreground.
  5. Right-click tray → menu shows Show / Randomize Active Adapter / Exit. Each one fires.
  6. Apply MAC on Dashboard → Recent History row's Time column reads "just now". After ~5 min → "5 min ago".
  7. Filter Recent History by adapter name → grid filters live.
  8. Settings → Export → save dialog opens with JSON filter; pick a path → file written.
  9. Settings → Import → open dialog → pick a file → settings reloaded.
  10. Settings → Export All (zip) → save → unzip the result → settings.json + blacklist.json + history.json inside.
  11. Log → Export Log → save dialog with .txt / .log choices → file written.
  12. Tail %LOCALAPPDATA%\RandomMac\logs\log-*.txt after cold launch — each adapter logs exactly once.
  13. Restart app — log shows Auto update check: status=… after ~5 seconds (skipped silently if last check < 24h ago).

Compatibility

  • Windows 11 (Mica) / Windows 10 22H2 (Acrylic fallback) / older (solid backdrop).
  • x64 only. ARM64 not supported in this release.
  • Bundled WinAppSDK runtime + .NET 11 (~225 MB self-contained).
  • Building from source needs the .NET 11 preview SDK (global.json pinned); see DEV_ENVIRONMENT.md.
