How do I register services in .NET MAUI?

Services are registered in the MauiProgram.cs file using the builder.Services collection within the CreateMauiApp method, allowing for centralized configuration.

How do I handle platform-specific dependencies in DI?

You can use preprocessor directives like #if ANDROID or #if IOS inside your registration logic to bind interfaces to their platform-specific implementations.

Should I use Singleton or Transient for ViewModels?

It is standard practice to use AddTransient for ViewModels and Pages to ensure fresh instances are created, while AddSingleton is reserved for shared or expensive services.

Does .NET MAUI support constructor injection?

Yes, constructor injection is the preferred method for resolving dependencies in .NET MAUI, where the DI container automatically provides required services to classes.

Configures and manages dependency injection patterns for .NET MAUI applications to ensure modularity and testability.

This skill provides specialized guidance for implementing Dependency Injection (DI) in .NET MAUI applications. It covers essential patterns including service registration in MauiProgram.cs, choosing between Singleton and Transient lifetimes, and implementing constructor injection for ViewModels and Pages. It also provides advanced techniques for automatic resolution during Shell navigation, platform-specific service implementation using preprocessor directives, and interface-first design to facilitate easier unit testing and mocking.
