In .NET development, maintaining clean and readable code is crucial. One technique to achieve this is by leveraging extension methods for initializing Dependency Injection (DI) containers. This approach aligns with the principles of clean architecture by ensuring each part of the application has a single responsibility. Extension methods encapsulate DI setup code, keeping it close to the actual code it relates to. By organizing registrations into reusable configurations, developers can reduce noise in Program.cs and promote better organization, modularity, and reusability.
