Avoiding Code Bloat: Mastering ISP for Cleaner C# Interfaces

The Interface Segregation Principle (ISP) is one of the five SOLID principles of object-oriented design. It ensures that a class is not forced to implement interfaces it does not use. This principle promotes smaller, more specific interfaces rather than large, general-purpose ones.

In this article, we’ll explore the concept of ISP in C#, why it matters, and how to implement it effectively.

What Is the Interface Segregation Principle?

The principle states:

“A client should not be forced to depend on methods it does not use.”

In simpler terms, if a class is forced to implement methods that it doesn’t need, it creates unnecessary dependencies. These dependencies can lead to issues like code bloat, reduced maintainability, and increased testing overhead.

Why Is Interface Segregation Important?

1. Improves Code Readability: Smaller, focused interfaces are easier to understand and implement.
2. Enhances Maintainability: Changes to one interface do not impact unrelated parts of the code.
3. Reduces Coupling…
