phase: 10-branding-data-foundation
plan: "03"
subsystem: infra
tags: [di, dependency-injection, ioc-container, branding, graph-directory, wpf]
# Dependency graph
requires:
- phase: 10-branding-data-foundation-01
provides: "BrandingRepository, IBrandingService/BrandingService"
- phase: 10-branding-data-foundation-02
provides: "IGraphUserDirectoryService/GraphUserDirectoryService"
provides:
- "BrandingRepository registered as Singleton in DI (branding.json path)"
- "IBrandingService/BrandingService registered as Singleton in DI"
- "IGraphUserDirectoryService/GraphUserDirectoryService registered as Transient in DI"
- "Phase 10 services fully wired — resolvable at runtime"
affects:
- phase-11-report-branding
- phase-13-user-directory-viewmodel
- phase-14-user-directory-ui
# Tech tracking
tech-stack:
added: []
patterns:
- "Phase 10 DI block placed after SettingsRepository, before MsalClientFactory — grouped with other repository/infrastructure singletons"
- "BrandingRepository: Singleton lifetime matching ProfileRepository/SettingsRepository (single file, shared SemaphoreSlim)"
- "IBrandingService: Singleton lifetime — stateless after construction, depends on singleton BrandingRepository"
- "IGraphUserDirectoryService: Transient lifetime — stateless, per-call, designed for multiple-tenant scenarios"
key-files:
created: []
modified:
- SharepointToolbox/App.xaml.cs
key-decisions:
- "No new using statements required — SharepointToolbox.Infrastructure.Persistence and SharepointToolbox.Services were already imported from prior phases"
patterns-established:
- "Phase section comment pattern: each new phase block labeled with '// Phase N: Name' comment for orientation in RegisterServices"
requirements-completed:
- BRAND-01
- BRAND-03
- BRAND-06

# 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
