Cannot create instance of type 'Syncfusion.UI.Xaml.Schedule.ScheduleAppointmentEditor'

After Windows 10 update, which i don't know what exactly, some pcs cannot open the calendar functionality with error Cannot create instance of type 'Syncfusion.UI.Xaml.Schedule.ScheduleAppointmentEditor'

We have a calendar functionality, which is not working anymore.

Example(part of the code) : 


WeekSchedule = new SfSchedule();

 // Sets appointment Template

WeekSchedule.AppointmentTemplate = (DataTemplate)this.Resources["CalendarAppointmentDataTemplate"];

WeekSchedule.HeaderDateFormat = "dddd dd";

WeekSchedule.IntervalHeight = 50;

#region List of appointments binding

Binding appointments = new Binding();

appointments.Source = vm;

appointments.Path = new PropertyPath("FilteredScheduleAppointments");

appointments.Mode = BindingMode.TwoWay;

WeekSchedule.SetBinding(SfSchedule.AppointmentsProperty, appointments);


We have two versions of the same application and nearly same code (same for the calendar functionality)

On WinRT, doesnt work anymore, but on UWP, the functionality is working correctly

Anyone can help?

Thanking you in ad

#Regarding Cannot create instance of type 'Syncfusion.UI.Xaml.Schedule.ScheduleAppointmentEditor 
The reported issue has been fixed and included in the patch which can be download from the below links.

Assemblies Link:    
   
Nuget link:     
   
    
Assembly Version: 14.4.0.15    
    
Installation Directions:    
This patch should replace the files "Syncfusion.SfSchedule.WinRT” under the following folder.

If this option is unchecked, the patch will replace the assemblies in precompiled assemblies’ folder only.

Hello,


Im using Visual Studio Enterprise 2015, and when i run the installer, it says that it is configured for the Essential Studio Version.


Any solution?


When i try to import the library manually, 

since i have other Syncfusion libraries such as :

SfChart.WinRT, SfGauge.WinRT,SfGrid.WinRT Syncfusion.Data.WinRT etc they also need to be the same version as the new SfSchedule, (list added as attachement)

any area where i can get it?

Hello,


Even after using the new libraries it doesn't work.

Issue occurred when we installed windows version 20H2

the framework causing issues is : 528372 (20H2)

Everything works fine on framework: 528040 (1909)


UWP versions works fine with WinRT libraries (v13.3810.0.7) under the framework 528372


at that point, should i consider that WinRT libaries for syncfusion doesnt work under 20H2 windows versions?


Thanking you in advance

Hello,


Ill wait for your reply. I have created a basic application with a basic scheduler, see photo in the attached zip file.

In the designer, the scheduler can be seen clearly, but when running the basic application, it breaks down with the same error.


Thanking you in advance.

Brice
