🚀 C# ASP.NET Core 10 Fundamentals

Welcome to the ultimate C# ASP.NET Core 10 learning and development playground! This repository is meticulously structured to follow industry-leading best practices, from Domain-Driven Design (DDD) to 100% Test Coverage and modern Utility-First Frontend Architectures.

Note

This project is the successor to C-Sharp-OOP-Fundamentals.

🏗️ Core Architecture & Design

We adhere to the following architectural pillars:

• 📐 DDD (Domain Driven Design): Focus on the core domain, bounded contexts, and ubiquitous language.
• 🏗️ Clean Architecture: Strict separation of concerns using MVC and Onion principles.
• 🎨 OOCSS & Atomic Design: Styling is structured via modules (e.g., theme.css, buttons.css) to ensure predictable scalable UIs.
• 🧱 SOLID: The foundation for modular and scalable C# systems.

---

🛡️ Code Quality Guidelines

Important

Quality is non-negotiable. We follow a zero-compromise policy on code quality, including exhaustive C#-XML (<summary>) documentation per IHK standards.

• 🧪 TDD (Test Driven): Red-Green-Refactor is our heartbeat.
• 📈 100% Coverage: Every logic branch verified via xUnit.
• ✨ DRY & KISS: Don't Repeat Yourself. Keep It Simple, Stupid.
• 📄 1 Class per File: Exceptionally clean file organization.

---

⚙️ Workflow & CI/CD

• 🧩 SFC (Single File Components): Modular UI architecture for Blazor and Razor.
• 🚀 Automated Tooling: Quality gates, linting, and automated builds.
• 📝 Documentation: Extensive Kdoc in every unit and Architectural Decision Records (ADR).
