Phase 1 Plan 06: WPF Shell Summary
FeatureViewModelBase with AsyncRelayCommand/CancellationToken/IProgress pattern + full WPF shell (Toolbar, 8-tab TabControl with FeatureTabBase, LogPanel, live-StatusBar) wired to Serilog, DI, and global exception handlers
Performance
- Duration: 5 min
- Started: 2026-04-02T10:28:10Z
- Completed: 2026-04-02T10:33:00Z
- Tasks: 2
- Files modified: 12
Accomplishments
- FeatureViewModelBase implements full async operation lifecycle: CancellationTokenSource creation/disposal, IsRunning guard on RunCommand.CanExecute, IProgress dispatching ProgressUpdatedMessage, OperationCanceledException caught gracefully, generic Exception caught with error message, finally block ensures IsRunning=false
- MainWindowViewModel subscribes to ProgressUpdatedMessage via WeakReferenceMessenger — StatusBar middle item shows live operation status text from any running feature ViewModel
- FeatureTabBase UserControl provides the canonical Phase 2 extension point: Row 0 contains the "coming soon" stub, Row 1 contains the progress/cancel strip (Visibility bound to IsRunning)
- All 7 stub feature TabItems use
<controls:FeatureTabBase />— none contain bare TextBlocks - App.xaml.cs registers all services in DI, wires LogPanelSink to the RichTextBox after MainWindow is resolved from the container, and installs both DispatcherUnhandledException and TaskScheduler.UnobservedTaskException handlers
- All 42 unit tests pass (6 new FeatureViewModelBase + 36 existing), 1 skipped (interactive MSAL), 0 errors, 0 warnings

Decisions Made
ObservableRecipientlambda receivers need explicit cast:Messenger.Register<T>types therparameter asobjectin the lambda signature; calling an instance method requires((FeatureViewModelBase)r).Method()for correct virtual dispatch.FeatureViewModelBasedeclared asabstract partial class— CommunityToolkit.Mvvm source generator generates a companion partial class for[ObservableProperty]attributes; plainabstract classcauses CS0260 missing partial modifier.OpenFolderDialog(Microsoft.Win32) used instead ofFolderBrowserDialog(System.Windows.Forms) — WPF-only project does not reference WinForms;OpenFolderDialogavailable natively in .NET 8+ viaMicrosoft.Win32.LogPanelexposed viaGetLogPanel()method —x:Name="LogPanel"in XAML generates a backing field in the generated partial class; adding a property with the same name causes CS0102 duplicate definition error.
Deviations from Plan
Auto-fixed Issues
1. [Rule 3 - Blocking] Added partial modifier to FeatureViewModelBase
- Found during: Task 1 (dotnet test — GREEN attempt)
- Issue: CS0260 — CommunityToolkit.Mvvm source generator produces a companion partial class for
[ObservableProperty]; class declared withoutpartialkeyword causes conflict - Fix: Changed
public abstract class FeatureViewModelBasetopublic abstract partial class FeatureViewModelBase - Files modified:
SharepointToolbox/ViewModels/FeatureViewModelBase.cs - Verification: Build succeeded, 6/6 FeatureViewModelBaseTests pass
- Committed in:
3c09155(Task 1 commit)
2. [Rule 1 - Bug] Fixed ObservableRecipient lambda receiver type
- Found during: Task 1 (dotnet test — GREEN attempt)
- Issue: CS1061 — Messenger.Register lambda types
rasobject; callingr.OnTenantSwitched()fails because method is not defined onobject - Fix: Added explicit cast:
((FeatureViewModelBase)r).OnTenantSwitched(m.Value) - Files modified:
SharepointToolbox/ViewModels/FeatureViewModelBase.cs - Verification: Build succeeded, tests pass
- Committed in:
3c09155(Task 1 commit)
3. [Rule 3 - Blocking] Replaced FolderBrowserDialog with OpenFolderDialog
- Found during: Task 2 (dotnet build)
- Issue:
System.Windows.Formsnamespace not available in WPF-only project;FolderBrowserDialogimport fails - Fix: Replaced with
Microsoft.Win32.OpenFolderDialog(available in .NET 8+ natively) and updated method accordingly - Files modified:
SharepointToolbox/ViewModels/Tabs/SettingsViewModel.cs - Verification: Build succeeded with 0 errors
- Committed in:
5920d42(Task 2 commit)
4. [Rule 3 - Blocking] Exposed LogPanel via GetLogPanel() method instead of property
- Found during: Task 2 (dotnet build)
- Issue: CS0102 —
x:Name="LogPanel"in XAML generates a field in the partial class; defining a propertyLogPanelin code-behind causes duplicate definition - Fix: Renamed the accessor to
GetLogPanel()method; updated App.xaml.cs to callmainWindow.GetLogPanel() - Files modified:
SharepointToolbox/MainWindow.xaml.cs,SharepointToolbox/App.xaml.cs - Verification: Build succeeded with 0 errors
- Committed in:
5920d42(Task 2 commit)
5. [Rule 1 - Bug] Used correct resx key names (tab.search, tab.structure)
- Found during: Task 2 (XAML authoring)
- Issue: Plan referenced
tab.filesearchandtab.folderstructurebut Strings.resx from plan 01-05 definestab.searchandtab.structure - Fix: Used the actual keys from Strings.resx:
tab.searchandtab.structure - Files modified:
SharepointToolbox/MainWindow.xaml - Verification: Build succeeded; keys resolve correctly via TranslationSource
- Committed in:
5920d42(Task 2 commit)
Total deviations: 5 auto-fixed (2 Rule 1 bugs, 3 Rule 3 blocking build issues) Impact on plan: All fixes necessary for compilation and correct operation. No scope creep. Plan intent fully preserved.
Issues Encountered
None beyond the auto-fixed deviations above.
User Setup Required
None — no external service configuration required.
Next Phase Readiness
- FeatureViewModelBase ready for all Phase 2 feature ViewModels to inherit — override
RunOperationAsyncand callRunCommand.ExecuteAsync(null)from UI - FeatureTabBase Row 0 is the Phase 2 extension point — replace the stub TextBlock row with real feature content
x:Name="SettingsTabItem"on Settings TabItem — plan 01-07 can replace the placeholder TextBlock with SettingsView- MainWindowViewModel.ManageProfilesCommand wired — plan 01-07 opens ProfileManagementDialog using ProfileManagementViewModel
- All 42 unit tests green; 0 build errors/warnings — foundation ready for Phase 2 feature planning
