ContosoUniversity Migration Test

End-to-end migration benchmark that converts the ContosoUniversity Web Forms sample to Blazor Server and validates with 40 Playwright acceptance tests.

Paths

| Item | Path | |------|------| | Web Forms source | samples/ContosoUniversity/ContosoUniversity/ | | Blazor output | samples/AfterContosoUniversity/ | | L1 script | migration-toolkit/scripts/bwfc-migrate.ps1 | | Migration skills | migration-toolkit/skills/ (4 skills) | | Acceptance tests | src/ContosoUniversity.AcceptanceTests/ | | Run reports | dev-docs/migration-tests/contosouniversity/ |

Prerequisites

• .NET 10 SDK
• SQL Server LocalDB with ContosoUniversity database (attach samples/ContosoUniversity/ContosoUniversity.mdf if needed)
• Playwright browsers installed (run pwsh bin/Debug/net10.0/playwright.ps1 install from test project after first build)

Workflow

Phase 0: Preparation

1. Determine run number — Count existing runNN folders in dev-docs/migration-tests/contosouniversity/ and use the next sequential number
2. Record start time — Capture wall-clock time for overall timing
3. Clear output folder — Delete all contents of samples/AfterContosoUniversity/ but keep the directory itself

Phase 1: Layer 1 — Automated Script

Expected duration: < 2 seconds

1. Start L1 timer
2. Run the migration script:

powershell .\migration-toolkit\scripts\bwfc-migrate.ps1 -Path samples\ContosoUniversity\ContosoUniversity -Output samples\AfterContosoUniversity -Verbose

1. Stop L1 timer — record duration and transform count from script output
2. Verify: .razor files created, no .aspx files in output

Phase 2: Layer 2 — Copilot-Assisted Transforms

Expected duration: 20–30 minutes

Load and apply the migration toolkit from migration-toolkit/:

• Read migration-toolkit/README.md for the overall approach and key principles
• Read migration-toolkit/skills/ — the toolkit contains all the skills needed for the repair phase; apply whichever skills are relevant to the errors and patterns encountered in the generated output

Key transforms to execute:

• Convert code-behind lifecycle (Page_Load → OnInitializedAsync)
• Wire SelectMethod as SelectHandler<ItemType> delegates (NOT Items=)
• Create EF Core DbContext with SQL Server LocalDB connection
• Create Program.cs with DI registration for all BLL services
• Convert Site.Master → MainLayout.razor
• Migrate BLL classes to use EF Core + DI (IDbContextFactory)
• Wire all CRUD operations (Create, Read, Update, Delete) to UI

Phase 3: Build Validation

1. Run dotnet build samples\AfterContosoUniversity\
2. Fix compilation errors iteratively until 0 errors achieved
3. Record final error and warning counts

Phase 4: Acceptance Tests

1. Start the Blazor app in the background:

powershell $env:ASPNETCORE_URLS = "http://localhost:44380" dotnet run --project samples\AfterContosoUniversity\

1. Wait for HTTP 200 from http://localhost:44380
2. Run acceptance tests:

powershell $env:CONTOSO_BASE_URL = "http://localhost:44380" dotnet test src\ContosoUniversity.AcceptanceTests\ --verbosity normal

1. Record: total tests, passed, failed, skipped
2. Stop the Blazor app

Phase 5: Report Generation

1. Create dev-docs/migration-tests/contosouniversity/runNN/
2. Generate REPORT.md using REPORT-TEMPLATE.md
3. All sections required — even failed runs get a full report

Critical Rules

| Rule | Detail | |------|--------| | Database | SQL Server LocalDB — never SQLite | | Connection | Server=(localdb)\mssqllocaldb;Database=ContosoUniversity | | SelectMethod | Preserve as SelectHandler<ItemType> delegate — never convert to Items= | | L1→L2 handoff | No manual fixes between layers — L2 starts from raw L1 output | | Report every run | Even failed/partial runs get a report documenting what went wrong | | ItemType | Use ItemType (not TItem) for all data-bound component type parameters |

Reference Documents

• REPORT-TEMPLATE.md — Standard report format with all required sections
