I need my existing Xamarin Forms mobile application fully migrated to .NET MAUI so it builds and runs flawlessly on both iOS and Android. The current codebase follows MVVM, uses Xamarin Essentials and local SQLite storage, and includes a few custom renderers; all of that functionality must remain intact in the new MAUI version. While you are inside the codebase, I also want to introduce two new capabilities: – Push notifications (FCM for Android, APNs for iOS) connected to the REST back-end that already emits notification payloads. – Email/password user authentication with secure token refresh, calling my existing API endpoints. Deliverables • A clean .NET MAUI solution that compiles in Visual Studio 2022 (or later) with signed Release builds for both iOS and Android. • Fully implemented push notification and authentication modules, coded in C# with clear comments. • Step-by-step setup and build instructions in a README so I can reproduce the builds locally. • Source-control history that makes migration steps and feature additions easy to trace. I will supply the current Xamarin Forms repository, API documentation, Apple provisioning profiles, FCM keys, and test credentials as soon as the project starts. Maintainable code, performance parity with the original app, and smooth user experience on both platforms are the acceptance criteria.
