Xamarin.Forms to .NET MAUI Migration Skill

Purpose

Use this skill to migrate Xamarin.Forms code into .NET MAUI projects with a repeatable, auditable workflow.

This skill is reusable across repositories and teams. It supports full-solution migration and incremental copy-paste migration where code is moved module-by-module into an existing or new MAUI app.

This skill is designed around Microsoft guidance:

1. Upgrade Xamarin.Forms app to latest 5.x baseline.
2. Create a new .NET MAUI project.
3. Copy and transform code, resources, dependencies, and platform assets.
4. Replace incompatible APIs and modernize architecture.
5. Validate and report migration readiness and remaining manual work.
