What problem does it solve?

This skill provides a guided approach to implementing reliable dependency injection and layered architecture patterns in C#/.NET backend projects, helping teams maintain consistency and testability across services.

Core Features & Use Cases

• DI registration patterns for transient, scoped, and singleton services and how to wire them in Program.cs/Startup.cs.
• Service and repository layering with interface contracts and constructor injection examples.
• Examples of common patterns (factory-based service creation, repository interfaces, and unit-tested service layers) illustrated in a typical WebAPI or MVC backend.
• Use Case: rapidly scaffold a new backend feature with clean architecture while preserving testability and maintainability.

Quick Start

Use this skill to design and implement a cohesive backend module in a C#/.NET project, starting from defining interfaces for services and repositories, registering dependencies in the DI container, and wiring controllers to the service layer.
