This "WPF BusyIndicator | Developer Focused Examples | Telerik UI for WPF " sample set found at this url:
Tried to build this sample as WPF with the new "Telerik.Windows.Controls.for.Wpf.2021.1.223" library. The BusyIndicator does not appear. Nothing seems to happen.
Trying to understand how "RadBusyIndicator" works so it can be used in my application.
