Where is mapping done for xmlns to the classes in WPF?

2018-06-12 01:00:18
It is said that when xmlns is specified with the uri http://schemas.microsoft.com/winfx/2006/xaml/presentation, it brings in the definition or voaculbalry of classes from presentationframework dll.
I am curious, where is the mapping for the done ? (this question is not of practical significance, i am just curious and trying to understand wpf)
