dependencyProperty is a null reference (Nothing in Visual Basic).

This method is useful inside the GetValue override implementation. Typically, the GetValue override code invokes the GetValueBase, and then adds additional code.

For implementing the GetValue override, PropertyMetadata can be used in Register/RegisterAttached calls.
