.NET MAUI › Migration from Xamarin.Forms

How do namespaces and using directives change from Xamarin.Forms to MAUI?

Intermediate

Answer

Xamarin.Forms types move to Microsoft.Maui and Microsoft.Maui.Controls. Xamarin.Essentials merges into Microsoft.Maui.* namespaces. Update using directives and XAML namespace declarations (the default xmlns changes to the MAUI schema). Global usings can reduce repetitive imports.

// Xamarin.Forms
using Xamarin.Forms;
// MAUI
using Microsoft.Maui;
using Microsoft.Maui.Controls;

Real-world example A migration sweeps the codebase replacing Xamarin.Forms usings with Microsoft.Maui equivalents and updates the XAML root xmlns.
