What are some best practices or tips for naming and organizing your interfaces and dependencies?

Creo que es temática es la más simple y a la vez la más difícil del mundo del desarrollo. Algo tan sencillo como dar nombre a las cosas acaba convirtiéndose en muchos casos en autenticas pesadillas para entender la funcionalidad de muchas partes del código. Cada lenguaje tiene su propio estándar, pero más allá de las convenciones recomiendo simplemente sentido común busca un nombre que si lo vuelves a leer o se lo das a alguien a leer puede entender con mayor o menor precisión lo que hace. Por ejemplo: nombres relacionados con Data suelen ser en la mayoría de casos demasiado simples, hazte una pregunta: ¿Qué tipo de dato es Data?

1) Always use specific, meaningful, and self-descriptive names.  2) Prefix interfaces with "I" to distinguish them from concrete implementations.  3) Adhere to specific naming conventions followed in your company. 4) Organize interfaces and dependencies into logical groups based on their functionality or domain.  5) Avoid bloating interfaces with unrelated methods or responsibilities. 6) Split interfaces that are very large into smaller and more specific ones. (Interface segregation principle) 7) If interfaces are part of a public API, consider versioning them carefully to maintain backward compatibility. 8) Provide clear and concise documentation.

Naming interfaces and dependencies effectively is important for maintaining clean, lucrative and maintainable code. One can try following practices, 1.) Use clear and descriptive names for interfaces and dependencies to effectively showcase their purpose and functionality. 2.) One interface -> single responsibility. 3.) Group related components together in namespaces, packages, or modules based on their functionality. This makes it easier to understand the purpose of each component. 4.) Try to provide brief documentation for better understanding.

Here are some key titles for naming and organizing interfaces and dependencies: 🔸 Descriptive Names: Choose names that clearly indicate the purpose of the interface. For example, in a banking application, IAccountService is better than IService. 🔸 Consistency: Be consistent with naming conventions. If you're using I prefix for interfaces in C#, stick to it throughout. 🔸 Domain-Specific: Use names that are specific to your domain. For example, ITransactionRepository in a banking application. 🔸 Avoid Abbreviations: Unless it's a widely accepted one, avoid abbreviations. ITransactionRepository is better than ITransRepo.

Totally agree! I've found that clear, descriptive names—like `IRepository` instead of `IManager`—make code easier to understand and maintain, especially in team environments. Sticking to naming conventions also helps keep everything consistent and intuitive.

Interface solves the problem of multiple inheritance in C#. By following ISP, we can effectively have client centric interfaces which can be implemented/inherited wherever required without bloating.

Absolutely! I've applied ISP in some projects and saw a big difference in flexibility and testability. Smaller, focused interfaces like `ICustomerRepository` and `ICustomerNotifier` make dependencies clearer and keep implementations clean. It also helps avoid changes in one method affecting unrelated parts of the code.

Adhering to the ISP involves creating small, specific interfaces rather than large, monolithic ones. This practice ensures that clients only need to implement the methods relevant to their requirements, promoting a more modular and maintainable codebase.

Totally agree! I've used this approach often to make tests faster and more reliable. Injecting mocks for interfaces like `IEmailSender` removes the need for real email services during tests—no external calls, no waiting, and full control over behavior. It’s one of the reasons I always design with interfaces from the start.

Use dependency injection to manage dependencies and facilitate unit testing. This practice allows for the injection of dependencies into components, promoting flexibility and testability. Additionally, use mocking frameworks to simulate dependencies during unit testing, ensuring that tests focus on specific components.

This approach involves categorizing your codebase into distinct layers, such as presentation, business logic, and data access layers, and organizing them based on the features they support. This enables you to easily locate and understand relevant components, fostering efficient collaboration and reducing the risk of introducing unintended side effects during development or modifications.

That’s a great point! I’ve followed both structures depending on the project size. For larger apps, feature-based organization often makes things easier to navigate and scale—especially when multiple teams work on different domains. Layered architecture still works well for simpler or more traditional apps. The key for me is consistency and clarity—whatever structure you choose, it should help new developers onboard quickly and reduce cognitive load.

1. Identify different responsibilities or concerns within your code. 2. Break down complex functionalities into smaller, cohesive units that handle specific tasks. For example, separate user input handling from data processing or separate file operations from data manipulation. 3. Ensure that each class or module encapsulates a single responsibility. 4. Avoid bundling unrelated functionalities together. 5. By keeping each class focused, you enhance code readability and make it easier to understand and maintain.

Completely true! I’ve followed this approach in past projects, and it really makes the code more modular and easier to maintain.

Regularly review and refactor your interfaces and dependencies as the project evolves. Solicit feedback from team members and leverage code reviews to identify opportunities for improvement. Additionally, stay informed about evolving best practices and patterns to continuously enhance the design and organization of your code.
