the Schedule control still have a massive performance problem which makes it unuseable in productive app.
This was discussed here before, but its still present in 184.108.40.206 (Tested with UWP).
The problem occurs when you want to replace the ScheduleAppointments collection (e.g removing or adding appointments, changing date range).
I can't belive that I'm the only one struggling with that problem, or I miss some point completly.
The following pic shows a session using the Scheduler control, the action is to replace the current ScheduleAppointments collection (with one appointment) with a new ScheduleAppointments collection (with two appointments).
This takes a lot of time, see red circles.
