# The future of Microsoft MAUI (and Xamarin Forms)

Since Google seems to like my post about the future of Xamarin Forms so much (and I have a slight history of such posts), I’d figure I’d post an update about interesting things happening in the Xamarin Forms repo specifically related to MAUI.

### Renaming

The change that actually made me write this post - a large PR with 5000+ changed files that changes the Xamarin Forms name to MAUI.

Not much of a thing for actual functionality, but a significant symbolic milestone.

### Handlers and the great big architecture shift

.NET MAUI will completely change the way renderers are handled in Xamarin Forms. There are many advantages of doing it the new way, but the mechanics of how it is done are fairly complex. This video by Javier Suárez covers it well.

This is all happening right now in the main-handler branch.

#### Update

While I was writing this, work officially moved to the dotnet/maui repo and it is accepting pull requests directly.

### AppHost and Microsoft.Extensions

Originally an ASP.NET concept, that then migrated its way to Windows client development, this provides a common way to provide dependency injection, logging, and lots of other infrastructure stuff. In isolation, the pattern and implementation is good and will make it easier to override certain things in MAUI (such as handlers). It’s also useful in a wider sense since it will make configuring different styles of .NET apps more similar.

### Single project

Over the past couple of years there has been a move towards producing Xamarin libraries (and .NET libraries in general) using a single multi-targeted project. The most significant is probably Xamarin Essentials. This PR adds support for creating applications following the same pattern.

### Merging in Xamarin Essentials

There is a lot of functionality in Xamarin Essentials that Xamarin Forms would like to use. Likewise there is some functionality in Forms that is useful when not using Forms. This lead to some overlap in functionality (and occasionally overlap in APIs but not a perfect match in functionality).

There was an attempt to add Essentials as a dependency of Forms but it faced some problems, and there was a “change of plans”.

Now the solution is to have Forms and Essentials in the same repo. I hope Essentials remains available as its own Nuget package (and it looks like that will be the case).

### Resizetizer.NT

Resizertizer.NT, like its predecessor Resizetizer, is a package for generating platform specific images in all the right sizes at build time.

Managing image assets across iOS and Android (and using Visual Studio) has always been an unpleasant process. This tool makes it much easier and will be included in MAUI by default.
