How is WPF's DependencyObject implemented? [closed]

Question

Are there any articles that describe how the DependencyObject class in WPF works "under the hood"?

Specifically, I'm curious about how dependency properties are stored and accessed efficiently.

Answer 1

As we know, a dependency property can be defined only on types that subclass DependencyObject. This base class defines a key value dictionary, that contains the local values of dependency properties.

When a dependency property is accessed, it's value is dynamically resolved (via the GetValue(dependencyproperty) in the .Net wrapper). For greater detail, check here: http://wpftutorial.net/DependencyProperties.html
