Update Mobile App from VS2017 to VS2022

Question

My previous colleague developed a mobile App by using Visual Studio 2017 Xamarin, he quit 3 year ago, there are some API deprecated and it is required to be updated to Visual Studio 2022. This App will be useful for coming several years. I'm not sure migrate this App to .NET MAUI or still using Xamarin to update it. I'm familiar with Visual Studio, but novice to Xamarin and .NET MAUI. Any advice will be highly appreciated.

Hello,

This App will be useful for coming several years. I'm not sure migrate this App to .NET MAUI or still using Xamarin to update it.

As you said, this app will be useful for coming several years. But Xamarin support will end on May 1, 2024, please see Xamarin Support Policy.

Migrate this App to .NET MAUI is a better choose. Before you migrate this application, please read this document:Upgrade from Xamarin to .NET.

And If you migrate Xamarin.Forms to MAUI, Xamarin.Forms project must use Xamarin.Forms 4.8 or higher. However, for best success we recommend that your Xamarin.Forms project uses Xamarin.Forms 5.0, and .NET Standard 2.0 or higher.

It depends on whether the app is an xamarin forms app, if it is then you don't have much choice, you must convert it to Maui. However, if it is an Android-only app, then it is not necessary to convert it to Maui. You can bring it up to date to Android 14 and therefore it will still be viable on Google Play for at least a couple of years. Any further releases such as Android 15, will require conversion to net8_android or net9_android.
