Phase 04 Plan 05: BulkSiteService Implementation Summary

BulkSiteService implements IBulkSiteService using PnP Framework CreateSiteAsync for Team and Communication site bulk creation with per-site error handling

Performance

• Duration: 6 min
• Started: 2026-04-03T07:57:03Z
• Completed: 2026-04-03T08:02:15Z
• Tasks: 2 (both committed together)
• Files modified: 3

Accomplishments

• Implemented BulkSiteService with full IBulkSiteService contract
• Team site creation via TeamSiteCollectionCreationInformation with Alias, DisplayName, IsPublic=false, and Owners[]
• Communication site creation via CommunicationSiteCollectionCreationInformation with auto-generated URL from adminCtx.Url host
• Post-creation member/owner assignment via EnsureUser + AssociatedMemberGroup/OwnerGroup.Users.AddUser
• Per-site error handling delegates to BulkOperationRunner.RunAsync with continue-on-error semantics
• ParseEmails helper splits comma-separated owner/member CSV fields
• SanitizeAlias generates URL-safe aliases from display names
• 3 passing tests (interface check, default values, CSV field inspection) + 3 skipped (live SP required)

Task Commits

1. Task 1+2: Implement BulkSiteService + BulkSiteServiceTests - b0956ad (feat)

Files Created/Modified

• SharepointToolbox/Services/BulkSiteService.cs — Full IBulkSiteService implementation with PnP Framework
• SharepointToolbox.Tests/Services/BulkSiteServiceTests.cs — 3 passing + 3 skipped unit tests
• SharepointToolbox/Services/BulkMemberService.cs — Fixed pre-existing Group type ambiguity (Rule 1)

Decisions Made

• BulkSiteService imports SharepointToolbox.Core.Helpers not SharepointToolbox.Infrastructure.Auth — plan listed wrong using directive; ExecuteQueryRetryHelper lives in Core.Helpers as established by all Phase 2/3 services
• Communication site URL is constructed from adminCtx.Url hostname to ensure tenant-correct URLs without hardcoding

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed wrong using directive in BulkSiteService

• Found during: Task 1 (implementation)
• Issue: Plan code had using SharepointToolbox.Infrastructure.Auth; — ExecuteQueryRetryHelper is in SharepointToolbox.Core.Helpers
• Fix: Replaced using SharepointToolbox.Infrastructure.Auth; with using SharepointToolbox.Core.Helpers;
• Files modified: SharepointToolbox/Services/BulkSiteService.cs
• Commit: b0956ad

2. [Rule 1 - Bug] Fixed BulkMemberService.cs Group type ambiguity

• Found during: Task 1 (build verification)
• Issue: Group? targetGroup = null; on line 164 was ambiguous between Microsoft.SharePoint.Client.Group and Microsoft.Graph.Models.Group — CS0104 compile error
• Fix: Linter auto-applied using SpGroup = Microsoft.SharePoint.Client.Group; alias + used SpGroup?
• Files modified: SharepointToolbox/Services/BulkMemberService.cs
• Commit: b0956ad

---

Total deviations: 2 auto-fixed (2 x Rule 1 - compile bugs) Impact: Both fixes were required for compilation. No scope creep. BulkMemberService fix is out-of-scope (from a previous plan) but was blocking the build entirely.

Issues Encountered

The WPF temp project build lock (MainWindow.g.cs locked by another process) prevented dotnet build SharepointToolbox.slnx from completing. The test project build (dotnet build SharepointToolbox.Tests) succeeds normally and was used for verification.

User Setup Required

None — no external service configuration required.

Next Phase Readiness

• BulkSiteService is ready for use by BulkSiteViewModel (Plan 04-09) and BulkSiteView (Plan 04-10)
• All 3 non-skip tests pass; live integration tests remain skipped pending live SP admin context
• Build: dotnet build SharepointToolbox.Tests succeeds with 0 errors, 0 warnings

Self-Check: PASSED

• BulkSiteService.cs: FOUND at SharepointToolbox/Services/BulkSiteService.cs
• BulkSiteServiceTests.cs: FOUND at SharepointToolbox.Tests/Services/BulkSiteServiceTests.cs
• 04-05-SUMMARY.md: FOUND (this file)
• Commit b0956ad: FOUND
