WPF: Core Assemblies


The core WPF assemblies are:

WindowsBase.dll:-
This is the core types constituting the infrastructure of WPF API.

PresentationCore.dll:-
It defines numerous types constituting foundation of WPF GUI layer.

PresentationFoundation.dll:-
It defines WPF control types, animation & multimedia support, databinding suport and other WPF services.

Besides these three libraries WPF also uses an unmanaged binary called milcore.dll which acts as a bridge between WPF assemblies and DirectX runtime layer.
