.NET Development Skill

Zero-Fabrication | Test-Driven | Zero-Tolerance

This skill defines the mandatory standards for .NET development. These rules are non-negotiable and enforced to ensure consistency, maintainability, and correctness.

⚡ The Golden Rules

1. Real Tests Only: No mocks, no fakes. Tests must hit actual systems (DB, File, API).
2. Co-located Tests: Every file must have a #region Tests at the end.
3. Immutability: Use record types only. No public setters.
4. One Class Per File: File name must match type name exactly.
5. Zero Warnings: Warnings are errors. No exceptions.
6. "HOW" vs "WHAT": 95% of code in Common (Utilities), 5% in Features (Business Logic).
7. Document Everything: XML comments are MANDATORY for ALL public members, INCLUDING TEST METHODS.

📚 Documentation & Standards

• CODE_RULES.md: Coding standards, naming, style, and prohibited patterns.
• ARCH_RULES.md: Project structure, file organization, and architectural layers.
• TEST_RULES.md: Testing philosophy, patterns, and mandatory practices.
• SETUP.md: Project initialization, configuration, and templates.
• EXAMPLES.md: Reference guide to the included example files.

🛠️ Quick Start

1. Run the setup commands in SETUP.md.
2. Copy skills/Directory.Build.props to your src directory.
3. Follow ARCH_RULES.md for file placement.
4. Verify compliance with CODE_RULES.md and TEST_RULES.md before every commit.

IF YOU VIOLATE THESE RULES, YOU WILL FAIL.
