How do you implement scalable dependency injection in Xamarin applications?

Scalable DI in Xamarin uses IoC containers to manage object lifetimes, dependencies, and modular service registration.

Large Xamarin apps use DI containers like Microsoft.Extensions.DependencyInjection to register services with different lifetimes (Transient, Singleton, Scoped). This enables modular architecture, where each feature registers its dependencies independently. It improves testability, maintainability, and separation of concerns. Constructor injection ensures explicit dependency flow.
