❔ WPF derived combo box doesn't show up in namespace
I created a class derived from
System.Windows.Controls.ComboBox. I then rebuilt the DLL containing the combo box. Other controls show up in the list of controls ready to drop into my window. But not the combo box. Is there something that prevents controls not derived from System.Windows.Controls.UserControl from showing up? My class doesn't have a XAML file. Could that be it?
