I have attached the updated project, here are the changes I made:
1. removed common
namespace inside Appointments.xaml file as it is not needed.
2. changed "<schedule:InvertedBooleanConverter x:Key="InvertedBooleanConverter" />" to " <telerik:InvertedBooleanConverter x:Key="InvertedBooleanConverter" />" inside MainWindow.xaml - this change is required as previous we had this converter in both namespaces, now in the latest version it is available in only one place.
3. renamed "DragVisualCueItemTemplate" property of the ScheduleView to "DragVisualTemplate".
4. removed "ResizeArrowCueItemTemplate" property of the ScheduleView as it is not available anymore.
Hope this helps.
