FAQPage Schema
How do I migrate a Xamarin.Forms app to .NET MAUI?

To migrate a Xamarin.Forms app to .NET MAUI, align the project structure to a single-project MAUI setup, relocate cross-platform code into Platforms folders, update namespace mappings, and migrate renderers to handlers. This workflow minimizes build failures across Android, iOS, and macOS.

What is the best way to update custom renderers during a .NET MAUI migration?

The best way to update custom renderers during a .NET MAUI migration is to convert them to the handler architecture. This involves mapping renderer functionality to handler mappings and updating namespace references to ensure cross-platform compatibility.

Can I migrate a multi-project Xamarin.Forms solution to a single-project MAUI setup?

Yes, you can migrate a multi-project Xamarin.Forms solution to a single-project MAUI setup. This requires relocating platform-specific code into the respective Android, iOS, and macOS platform folders within the unified project structure.

How do I handle namespace renames when migrating to .NET MAUI?

Handling namespace renames during a .NET MAUI migration involves systematically replacing Xamarin.Forms namespaces with their corresponding MAUI equivalents. Applying these renames alongside project file updates and package replacements helps minimize build failures.

Does migrating Xamarin.Forms layouts to MAUI require data-store migration?

Yes, migrating Xamarin.Forms to MAUI often involves data-store migration alongside layout adjustments. The migration workflow includes cross-platform code relocation and platform-specific layout fixes to satisfy MAUI compatibility requirements.

What are common limitations when migrating to .NET MAUI?

Common limitations when migrating to .NET MAUI include project structure complexities, namespace mapping mismatches, and layout differences. Troubleshooting these migration issues requires addressing renderer-to-handler updates and applying field-tested best practices to resolve build failures.
