When building APIs with .NET, focus on a layered architecture from day one. Keep controllers thin and move business logic into services.
Use DTOs for incoming and outgoing models to avoid exposing internal entities directly.
Add centralized error handling, request validation, and proper logging so your API is easier to support in production.
For larger systems, split concerns by features and keep dependencies clear so your team can scale development safely.
