WPF - Architecture

Question

Hi Team,

I have read in the wpf architecture post, stating that "Most objects in WPF derive from DispatcherObject"

https://learn.microsoft.com/en-us/dotnet/desktop/wpf/advanced/wpf-architecture?view=netframeworkdesktop-4.8

It is most of the objects, means not all objects , so which/what kind of objects will not use the DispatcherObject.

Thanks

Answer 1

You could find objects that do not inherit from DispatcherObject here. Such as DispatcherEventArgs, DispatcherExtensions, Dispatcher, etc.
Update:
The following figure shows some of the main classes in the framework of the WPF class hierarchy (not all classes are included), which is helpful for a comprehensive understanding of the class hierarchy. The Brushes class in PresentationCore does not use DispatcherObject. It Implements a set of predefined SolidColorBrush objects.

You can see the Hierarchy, from WPF Dispatcher - Introduction and How to use? :
