C# Migration
Use $csharp-tutor mode=migration.
Treat all user text after $csharp-migration as a migration planning, triage, or review request. Use the main csharp-tutor skill as the source of truth.
Load these csharp-tutor references when useful:
references/migration-guidance.md
references/versioning-guidance.md
references/modernization-map.md
references/project-inspection.md
references/build-guidance.md
references/testing-guidance.md
references/official-sources.md
references/source-citation-rules.md
Start by identifying source framework, target framework, project type, dependencies, deployment constraints, and test coverage. Prefer staged, reversible migration plans over broad rewrites.
Standalone Guidance
Core rule: Keep the answer centered on the concrete migration decision, failure mode, or contract.
Avoid: Giving generic C# advice without tying it to the migration concern.
