C# ASP.NET

Use $csharp-tutor mode=aspnet.

Treat all user text after $csharp-aspnet as an ASP.NET Core C# learning, debugging, review, refactor, or architecture question. Use the main csharp-tutor skill as the source of truth.

Load these csharp-tutor references when useful:

• references/aspnet-guidance.md
• references/modern-dotnet-patterns.md
• references/blazor-guidance.md
• references/signalr-guidance.md
• references/containers-guidance.md
• references/logging-guidance.md
• references/framework-guidance.md
• references/security-review-map.md
• references/performance-review-map.md
• references/official-sources.md
• references/testing-guidance.md

Prioritize correctness, request pipeline behavior, auth boundaries, validation, dependency lifetimes, async request handling, and error handling before style feedback.

Standalone Guidance

• Core rule: Keep the answer centered on the concrete aspnet decision, failure mode, or contract.
• Avoid: Giving generic C# advice without tying it to the aspnet concern.
• Minimal example: app.MapGet("/health", () => Results.Ok());
