Short Answer
.NET MAUI is an advanced version of Xamarin.Forms that simplifies cross-platform development by unifying project structures, improving performance, and offering better extensibility. It replaces Xamarin.Forms’ renderer-based architecture with handlers and provides enhanced native integration with .NET 6+.
Long Answer
1. Introduction to .NET MAUI and Xamarin.Forms
Both .NET MAUI and Xamarin.Forms are Microsoft’s frameworks for building cross-platform applications, but .NET MAUI modernizes the development approach by offering a single project structure, better performance, and more flexibility in UI rendering.
2. Key Differences Between .NET MAUI and Xamarin.Forms
| Feature | .NET MAUI | Xamarin.Forms |
|---|---|---|
| Project Structure | Single project for all platforms | Separate projects for each platform |
| Performance | Optimized with .NET 6+ | Relies on older architecture |
| Rendering | Uses Handlers | Uses Renderers |
| Native API Access | Simplified integration | More complex customization |
| Blazor Integration | Yes | No |
| Supported Platforms | Android, iOS, macOS, Windows | Android, iOS, macOS (limited), Windows |
3. Project Structure and Code Simplification
- Xamarin.Forms: Developers needed to maintain separate projects for Android, iOS, and Windows, leading to increased complexity.
- .NET MAUI: Introduces a single project approach where all platform-specific configurations reside in one place, reducing code duplication.
4. Performance Improvements in .NET MAUI
- Faster Startup Time: .NET MAUI optimizes startup processes, reducing app load time.
- Memory Management: More efficient resource handling compared to Xamarin.Forms.
- Hardware Acceleration: Better support for graphics and animations.
5. UI Rendering: Handlers vs Renderers
- Xamarin.Forms Renderers: Used for platform-specific UI rendering but introduced performance overhead.
- .NET MAUI Handlers: A lightweight, flexible approach that improves customization and reduces rendering complexity.
6. Platform API Access and Customization
- Xamarin.Forms: Required dependency services and effects for platform-specific features.
- .NET MAUI: Allows direct access to native APIs and system controls with improved performance.
7. Blazor Integration in .NET MAUI
- Xamarin.Forms: No direct Blazor support.
- .NET MAUI: Enables Blazor Hybrid Apps, allowing web-based UI elements inside native applications.
8. Migration from Xamarin.Forms to .NET MAUI
Microsoft provides migration guides to transition from Xamarin.Forms to .NET MAUI smoothly. Key steps include:
- Updating the project structure to use the .NET 6+ single project format.
- Replacing renderers with handlers.
- Adapting platform-specific code for compatibility.
9. Why Choose .NET MAUI Over Xamarin.Forms?
- Modernized architecture for better performance.
- Single project approach simplifies development.
- Seamless integration with Blazor and .NET 6+.
- Long-term support from Microsoft.
10. Interview Tips and Final Thoughts
- Understand the architectural differences between .NET MAUI and Xamarin.Forms.
- Know how the transition from renderers to handlers improves performance.
- Be familiar with the migration process from Xamarin.Forms to .NET MAUI.
- Stay updated with the latest .NET MAUI developments and improvements.
