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".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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`, and `AddScoped`
- Wiring constructor injection for Pages and ViewModels
- Leveraging Shell navigation to auto-resolve DI-registered Pages
- Registering platform-specific service implementations with `#if` directives
- 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.cs` file
- Knowledge of which services, ViewModels, and Pages need registration

How to install

The exact contents, by fingerprint
mdr add dotnet/skills/maui-dependency-injection@sha256:0efbf7b9dd6c5da7

The line at the top of this page pins the label git:20260728.6d1201c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
