How do you implement scalable architecture in large Xamarin applications?

Scalable Xamarin apps use layered architecture like MVVM, clean separation of concerns, and modular services.

Scalability in Xamarin is achieved through architectural patterns such as MVVM combined with Clean Architecture or Hexagonal Architecture. The app is divided into layers: Presentation (UI), Domain (business logic), and Data (services/repositories). Dependency Injection ensures loose coupling. Feature-based modularization allows independent development of app components. This approach improves testability, maintainability, and team scalability.
