Phase 10 Plan 03: DI Registration Summary

BrandingRepository (Singleton), IBrandingService (Singleton), and IGraphUserDirectoryService (Transient) wired into App.xaml.cs — 224 tests pass, zero regressions

Performance

• Duration: ~5 min
• Started: 2026-04-08T10:34:43Z
• Completed: 2026-04-08T10:39:00Z
• Tasks: 1
• Files modified: 1

Accomplishments

• All three Phase 10 services registered in the application's DI container with correct lifetimes
• Main project builds with zero warnings under -warnaserror
• Full test suite: 224 passed, 26 skipped (integration tests requiring live Graph), 0 failed

Task Commits

Each task was committed atomically:

1. Task 1: Register Phase 10 services in DI and run full test suite - 7e8e228 (feat)

Files Created/Modified

• SharepointToolbox/App.xaml.cs - Added Phase 10 DI block: BrandingRepository (Singleton, branding.json), IBrandingService/BrandingService (Singleton), IGraphUserDirectoryService/GraphUserDirectoryService (Transient)

Decisions Made

None - followed plan as specified. The using directives for SharepointToolbox.Infrastructure.Persistence and SharepointToolbox.Services were already present, so no additional imports were needed.

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

One flaky test failure (CanExport_true_when_has_results) occurred during the first full suite run. This test uses WeakReferenceMessenger with async ViewModel operations and is timing-sensitive. Re-running the specific test and then the full suite both passed. The failure was not caused by my DI changes (the test uses direct constructor injection with mocks — no DI container involved). The test passed on all subsequent runs.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All Phase 10 services resolve at runtime without errors
• Phase 11 (report branding) can inject IBrandingService into export services and ViewModels
• Phase 13 (user directory ViewModel) can inject IGraphUserDirectoryService
• BrandingRepository will create branding.json on first write, in the existing AppData directory — no manual setup needed
