What it does
Guidance for configuring dependency injection in .NET MAUI apps, service registration in MauiProgram.cs, lifetime selection (Singleton / Transient / Scoped), constructor injection, Shell navigation auto-resolution, platform-specific registrations, and testability patterns. USE FOR: "dependency injection", "DI setup", "AddSingleton", "AddTransient", "AddScoped", "service registration", "constructor injection", "IServiceProvider", "MauiProgram DI", "register services", "BindingContext injection". DO NOT USE FOR: data binding (use maui-data-binding), Shell route configuration (use maui-shell-navigation), unit-test mocking frameworks (use standard xUnit and NSubstitute patterns).
Dependency Injection in .NET MAUI
.NET MAUI uses the same Microsoft.Extensions.DependencyInjection container as ASP.NET Core. All service registration happens in MauiProgram.CreateMauiApp() on builder.Services. The container is built once at startup and is immutable thereafter.
When to Use
- Registering services, ViewModels, and Pages in
MauiProgram.cs - Choosing between
AddSingleton,AddTransient, andAddScoped - Wiring constructor injection for Pages and ViewModels
- Leveraging Shell navigation to auto-resolve DI-registered Pages
- Registering platform-specific service implementations with
#ifdirectives - Designing interfaces for testable service layers
When Not to Use
- XAML data-binding syntax or compiled bindings, use the maui-data-binding skill
- Shell route registration and query parameters, use the maui-shell-navigation skill
- Mocking frameworks or test runners, use standard .NET testing tools (xUnit, NUnit, MSTest) and mocking libraries (NSubstitute, Moq)
Inputs
- A .NET MAUI project with a
MauiProgram.csfile - Knowledge of which services, ViewModels, and Pages need registration
- Target platforms (Android, iOS, Mac Catalyst, Windows) for conditional registrations
