To refactor a C# class violating the Single Responsibility Principle, split the complex class into smaller, focused classes, each handling only one unrelated task. This refactoring technique improves class design, maintainability, and testability.

SOLID design principles in C# include Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion. Applying these software design best practices improves code maintainability, extensibility, and testability.

Apply the DRY (Don't Repeat Yourself) principle in C# to reduce bugs and improve maintainability, but recognize when code duplication is acceptable. Guidance helps identify when forcing DRY creates unnecessary coupling versus when duplication is the cleaner approach.

Fix dependency management anti-patterns in C# by applying the Dependency Inversion Principle. This involves refactoring interface contracts and class design to manage dependencies properly, resulting in more robust, scalable, and testable code.

The best way to improve C# code maintainability and testability is applying SOLID and DRY design principles. Refactoring class designs and interface contracts through established software design best practices reduces bugs and scales complex codebases.
