A guide for building .NET MAUI apps, which use one codebase for mobile and desktop applications on Android, iOS, macOS, and Windows.

In plain words
What is it for?
Use it when building, reviewing, or moving Xamarin.Forms apps to MAUI, creating shared mobile or desktop screens, or connecting an app to platform-specific features.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dotnet-maui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

.NET MAUI

Trigger On

  • working on cross-platform mobile or desktop UI in .NET MAUI
  • integrating device capabilities, navigation, or platform-specific code
  • migrating Xamarin.Forms or aligning a shared codebase across targets
  • implementing MVVM patterns in mobile apps

Documentation

References

  • patterns.md - Shell navigation, platform-specific code, messaging, lifecycle, data binding, and CollectionView patterns
  • anti-patterns.md - Common MAUI mistakes and how to avoid them

Platform Targets

Platform Build Host Notes
Android Windows/Mac Emulator or device
iOS Mac only Requires Xcode
macOS Mac only Catalyst
Windows Windows WinUI 3

Workflow

  1. Confirm target platforms — behavior differs across Android, iOS, Mac, Windows
  2. Separate shared UI and platform code — use handlers and DI
  3. Follow MVVM pattern — keep views dumb, logic in ViewModels
  4. Handle lifecycle and permissions — platform contracts need testing
  5. Test on real devices — emulators don't catch everything

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
