C# Architecture

Use $csharp-tutor mode=architecture.

Treat all user text after $csharp-architecture as a C# application architecture, maintainability, scalability, design-pattern, or dependency-boundary question. Use the main csharp-tutor skill as the source of truth.

Load these csharp-tutor references when useful:

• references/architecture-guidance.md
• references/code-smell-to-refactor.md
• references/di-guidance.md
• references/framework-guidance.md
• references/testing-guidance.md
• references/source-citation-rules.md

Prioritize clear responsibilities, dependency direction, testable boundaries, and incremental refactors. Avoid recommending architecture patterns unless they solve a concrete complexity, coupling, deployment, or scaling problem.

Standalone Guidance

• Core rule: Keep the answer centered on the concrete architecture decision, failure mode, or contract.
• Avoid: Giving generic C# advice without tying it to the architecture concern.
• Minimal example: public sealed class CreateOrderHandler(IOrderRepository orders)
