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.
• Minimal example: <TargetFramework>net8.0</TargetFramework>
