Are you ready to build real cross-platform applications with modern .NET? .NET MAUI Fundamentals: Building Cross-Platform Applications with .NET 10 is a practical, architecture-first guide designed to help developers confidently create production-ready apps for Android, iOS, Windows, and macOS from a single codebase. Whether you are transitioning from Xamarin.Forms, expanding your .NET skills, or building your first multi-platform application, this book walks you step-by-step from setup to store deployment. This is not a surface-level overview. It is a structured, hands-on roadmap built for serious developers who want clean architecture, maintainable code, and real-world implementation strategies. What You Will Learn Build on a Modern Foundation - Understand the .NET MAUI handler architecture - Master the single project structure - Configure Android emulators and iOS simulators - Create and run your first cross-platform application Design Clean, Responsive Interfaces - Work effectively with XAML layouts and page architecture - Use CollectionView with optimized data templates - Implement robust data binding and value converters - Apply MVVM with dependency injection for scalable design Architect Real Applications - Implement SQLite and local storage strategies - Build repository layers and service abstractions - Consume REST APIs with HttpClient - Apply resilience patterns for remote data integration - Unit test ViewModels and services with proper mocking Leverage Advanced Capabilities - Create reusable custom controls - Extend handlers for platform-specific functionality - Access device sensors, camera, and geolocation - Implement OAuth 2.0 authentication and secure storage -Manage tokens, certificates, and identity providers securely Prepare for Production - Improve accessibility and localization - Optimize startup time and rendering performance - Diagnose memory and UI performance issues - Configure CI/CD pipelines - Publish to the App Store and Google Play Who This Book Is For - C# and .NET developers expanding into mobile and desktop - Xamarin developers migrating to .NET MAUI - Software engineers building enterprise cross-platform apps - Technical leads designing scalable multi-platform architecture Why This Book Is Different This guide emphasizes clean architecture, maintainability, and performance. Instead of quick demos, you will learn structured patterns that scale in real applications. By the end of this book, you will be able to: - Design maintainable cross-platform solutions - Integrate secure authentication workflows - Optimize performance across devices - Deploy confidently to production environments If you want to build modern cross-platform applications the right way using .NET 10 and .NET MAUI, this book provides the foundation.
