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.
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
