Frequently asked questions

When will Xamarin support end?

Xamarin support will end on May 1, 2024, for all Xamarin SDKs. Android 13 and Xcode 14 SDKs (iOS and iPadOS 16, macOS 13) will be the final versions that Xamarin will target.

What does it mean that Xamarin will not be supported?

This means that Microsoft will no longer provide fixes, updates, or technical assistance. In this scenario, your app may experience performance problems and become vulnerable due to the lack of security updates.
