Property Value


A dictionary that acts as an extensibility hook for developers to manipulate DependencyObject declarations for a design tool and associate custom data with individual activity declarations.



This property is a metaproperty, which means it is immutable at run time. Metaproperties do not change after a property instance is created at run time, so the property must be set to a literal value at design time.

This property is not used in the default Activity declaration implementations provided by Windows Workflow Foundation. This collection is not serialized; data that the collection contains is not persisted from design time to run time.
