- Attributes
Remarks
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.
