.NET MAUI Native Application Engineering

Build native apps that actually feel native - on Android, iOS, and Windows - from a single C# codebase.
Most cross-platform tutorials stop at "hello world." This book doesn't. Through the complete, chapter-by-chapter build of FieldSync, a real-world field service application for a fictional solar installation company, you'll go from a blank .NET MAUI project to a production-grade, three-platform application with offline-first data sync, custom native controls, hardware integration, and a working CI/CD release pipeline.
You won't just learn what the APIs do, you'll learn when to reach for them, when not to, and what happens when a real device, a real user, and a real spotty connection all show up at once.
Inside, you'll learn how to:

• Understand the handler architecture that lets MAUI produce genuinely native UI on every platform, not a web view wearing a costume
• Structure a maintainable MVVM codebase with dependency injection, testable ViewModels, and clean service abstractions
• Build fully custom native controls with your own handlers on Android, iOS, and Windows - including a hand-drawn signature capture control
• Integrate real device hardware: camera, GPS, Bluetooth, sensors, and even a proprietary native hardware SDK via custom bindings
• Design offline-first data sync that survives real connectivity gaps, with SQLite persistence and conflict-safe recovery logic
• Ship with confidence: unit and UI testing, crash diagnostics, and a multi-platform CI/CD pipeline that signs and deploys to Android, iOS, and Windows from one workflow
• Secure, version, and observe a production app once it's actually live in the field
