Xamarin Framework Deprecation
As of LEADTOOLS v23, The cross-platform Xamarin framework has been deprecated and replaced with LEADTOOLS .NET MAUI framework.
For any LEADTOOLS Xamarin apps you have already built, we recommend you migrate to the LEADTOOLS .NET MAUI framework. To help you with the migration, review the LEADTOOLS .NET MAUI tutorials to get you started.
This change is driven by Microsoft's announcement to end Xamarin support.
