SfSchedule 'ChromelessWindow' TargetType does not match type of element 'ScheduleReminderControl error at 17.4

I have a WPF app that works fine at 17.4.0.44

When upgraded to 17.4.0.46 the form does not show and I get this error:

InvalidOperationException: 'ChromelessWindow' TargetType does not match type of element 'ScheduleReminderControl'.

This is the stacktrace:

The project still compiles and the WPF form shows.

However some events are not triggered, e.g. drag and drop.


The XAML file is attached as a txt file.


When I move back to 17.4.0.44 everything works fine.
