CustomFindReplace, SpellCheckingDialogAttribute classes are not found

[Sagar]

CustomFindReplace, SpellCheckingDialogAttribute classes are not found inside using Telerik.Windows.Documents.UI.Extensibility; after I upgraded the wpf from net framework to net core. It works in my same net framework project.

Hi Sagar,

There is no MEF in NET Core or later, so you are getting these errors. More information is available here: WPF RichTextBox - MEF - Telerik UI for WPF

I hope this helps. Should you have any other questions do not hesitate to ask.
