Refactoring Messy Code: My Approach to Coupling and Cohesion
TL;DR: High cohesion means classes focus on one job. Low coupling means classes don’t depend too much on each other. When I refactor messy code, these two principles guide every decision I make. Why I Focus on Cohesion and Coupling When Refactoring After 10+ years of building enterprise applications, I’ve inherited my fair share of messy codebases. The pattern is always the same: tangled classes doing too much, components that break when you touch something seemingly unrelated, and tests that require half the application to run. ...
Prefer Interfaces Over Abstract Classes in C#: Build Flexible, Testable, and Maintainable Code
Learn why experienced C# developers choose interfaces over abstract classes 95% of the time. Real-world examples, team benefits, and clean architecture tips.
Dependency Inversion Principle in C#: Flexible Code with ASP.NET Core DI
Discover how the Dependency Inversion Principle makes your C# code flexible and testable. Learn to use ASP.NET Core DI to depend on abstractions, swap implementations, and build maintainable, scalable applications with real-world examples.
DIP vs DI vs IoC: Understanding Key Software Design Concepts
TL;DR: DIP (Dependency Inversion Principle): High-level modules should not depend on low-level modules; both depend on abstractions. DI (Dependency Injection): A technique to supply dependencies from outside a class, improving testability and flexibility. IoC (Inversion of Control): A broader concept where control of object creation and dependency resolution is delegated to a container or framework. Together, they enable decoupled, maintainable, and testable applications. DIP is a design principle, DI is a pattern, IoC is the overarching concept. Introduction If you’ve ever been in a job interview for a software developer position, chances are you’ve been asked to explain the difference between DIP, DI, and IoC. I know I have, and the first time I was asked, I definitely stumbled through my answer! ...
