What problem does it solve?

SOLID principles help you fix tangled object-oriented designs by making responsibilities clear, reducing coupling, and improving extensibility without repeatedly breaking existing code.

Core Features & Use Cases

• SRP (Single Responsibility): Spot god classes and methods doing multiple jobs, then split responsibilities into cohesive services and collaborators.
• OCP (Open/Closed): Replace fragile if/else or “modify existing code” patterns with extension via abstractions (e.g., strategies, polymorphism).
• LSP/ISP/DIP (Substitution, Segregation, Inversion): Improve inheritance correctness, avoid fat interfaces with unneeded methods, and inject dependencies through interfaces to make code easier to test and mock.
• Use Cases: Refactoring bloated services, designing feature growth without regressions, setting up .NET dependency injection correctly, and stabilizing unit tests that are brittle and hard to mock.

Quick Start

Ask the AI: “Refactor my C# class that does too many things using SOLID (SRP, OCP, LSP, ISP, DIP). Suggest an improved design and show how I should register dependencies with .NET DI, then outline how to write more reliable unit tests for it.”
