Maui Dependency Injection is an agent skill from davidortinau/maui-skills. Guidance for dependency injection in .NET MAUI apps — service registration, lifetime selection (Singleton/Transient/Scoped), constructor injection, automatic resolution via Shell navigation, explicit resolution patterns, platform-specific registrations, and testability best practices. USE FOR: "dependency injection", "DI registration", "AddSingleton", "AddTransient", "AddScoped", "service registration", "constructor injection", "IServiceProvider", "MauiProgram DI", "register services". DO NOT USE FOR: data…
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/dependency-injection-api.md`).
It sits in Mobile, covering Cross-platform mobile apps, Design patterns and Unit testing. The repository describes itself as: .NET MAUI skills for GitHub Copilot and Claude Code. The licence is MIT.
Read from SKILL.md and the folder at commit 79bb4bf. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are csharp).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Maui Dependency Injection loads about 1.3k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 168 tokens; SKILL.md has 271 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

|---|---|
| Does it hold shared state or is expensive to create? | AddSingleton |
| Is it stateless, lightweight, or per-request? | AddTransient |
Do you manage IServiceScope yourself? | AddScoped |
⚠️ Avoid
AddScopedin MAUI — there is no built-in scope per page. Using it without manually creatingIServiceScopegives you singleton behaviour silently, which is confusing and error-prone.
// ❌ ViewModel registered as Singleton — stale data across navigations
builder.Services.AddSingleton<DetailViewModel>();
// ✅ ViewModels are Transient — fresh instance each navigation
builder.Services.AddTransient<DetailViewModel>();Register Pages and ViewModels as Transient. Register services that hold shared state as Singleton (e.g.,
IDataService,HttpClientfactory).
XAML resources (App.xaml styles, converters) are parsed during
InitializeComponent() — before the DI container is fully available. If a
resource or converter needs a service, resolve it in CreateWindow(), not
in the constructor.
// ❌ Resolving services during XAML parse — container may not be ready
public App(IDataService data)
{
InitializeComponent(); // XAML parses here
_data = data; // may fail for types not yet resolved
}
// ✅ Defer service resolution to CreateWindow
public partial class App : Application
{
private readonly IServiceProvider _services;
public App(IServiceProvider services)
{
_services = services;
InitializeComponent();
}
protected override Window CreateWindow(IActivationState? activationState)
{
// Safe — container is fully built
var mainPage = _services.GetRequiredService<MainPage>();
return new Window(new AppShell());
}
}If a Page is used in Shell XAML (<ShellContent ContentTemplate="...">) but
not registered in builder.Services, MAUI instantiates it with the
parameterless constructor. Dependencies are silently null — no exception.
// ❌ Page not registered — constructor injection silently skipped
// builder.Services.AddTransient<DetailPage>(); // missing!
// ✅ Always register pages that need injection
builder.Services.AddTransient<DetailPage>();
builder.Services.AddTransient<DetailViewModel>();// ❌ Service locator scattered through code — hard to test, hides dependencies
public void DoWork()
{
var service = this.Handler.MauiContext.Services.GetService<IDataService>();
service.Load();
}
// ✅ Constructor injection — explicit, testable
public class MyViewModel(IDataService dataService)
{
public void DoWork() => dataService.Load();
}Use explicit resolution (
Handler.MauiContext.Services) only when constructor injection is genuinely unavailable (e.g., inside a custom handler or platform callback).
When using #if directives for platform services, ensure the interface
is always registered — otherwise consumers on untargeted platforms get a
runtime null.
// ❌ No registration on Windows — GetService returns null
#if ANDROID

Guidance for dependency injection in .NET MAUI apps — service registration, lifetime selection (Singleton/Transient/Scoped), constructor injection, automatic resolution via Shell navigation…. Maui Dependency Injection is an agent skill from davidortinau/maui-skills.NET MAUI apps — service registration, lifetime selection (Singleton/Transient/Scoped), constructor injection, automatic resolution via Shell navigation, explicit resolution patterns, platform-specific registrations, and testability best practices.
Maui Dependency Injection fits situations like: : dependency injection; DI registration; service registration; constructor injection.
Run `npx skills add davidortinau/maui-skills --skill maui-dependency-injection -a claude-code`. Or copy the skill folder (plugins/maui-skills/skills/maui-dependency-injection in davidortinau/maui-skills) into .claude/skills/maui-dependency-injection in your project. Claude Code loads it when a task matches its description.
Run `npx skills add davidortinau/maui-skills --skill maui-dependency-injection -a codex`. Or copy the skill folder (plugins/maui-skills/skills/maui-dependency-injection in davidortinau/maui-skills) into .agents/skills/maui-dependency-injection in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add davidortinau/maui-skills --skill maui-dependency-injection -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/maui-dependency-injection, .gemini/skills/maui-dependency-injection, .github/skills/maui-dependency-injection and .opencode/skills/maui-dependency-injection in your project.
SKILL.md names no scripts, command-line tools or credentials: Maui Dependency Injection is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Maui Dependency Injection is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.1k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Maui Dependency Injection: Maui Dependency Injection (dotnet/skills, 5.6k stars), Flutter Tester (FNOSP/FlyNarwhal, 509 stars), Bloc (VeryGoodOpenSource/vgv-ai-flutter-plugin, 170 stars) and Creating Reanimated Animations (gluestack/gluestack-ui, 5.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
