Teach and review Docker and containerization for C# and .NET applications. Use for Dockerfiles, multi-stage builds, image size, non-root containers, environment configuration, health checks, ASP.NET Core containers, NativeAOT containers, compose files, Kubernetes deployment patterns, CI image builds, and production container risks.

C# Containers
Use $csharp-tutor mode=containers.
Treat all user text after $csharp-containers as a .NET containerization, Docker, deployment, or review request. Use the main csharp-tutor skill as the source of truth.
Load these csharp-tutor references when useful:
references/containers-guidance.md
references/aspnet-guidance.md
references/aot-guidance.md
references/security-review-map.md
references/performance-review-map.md
references/build-guidance.md
references/official-sources.md
Prioritize reproducible builds, small runtime images, non-root execution, configuration boundaries, health checks, and deployment validation.
Standalone Guidance
Core rule: Keep the answer centered on the concrete containers decision, failure mode, or contract.
Avoid: Giving generic C# advice without tying it to the containers concern.
Minimal example: FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS runtime
