Microsoft Dynamics CRM workflow activities are layered over Windows Workflow Foundation activities. In each Microsoft Dynamics CRM workflow activity, the properties are specified when you create the class. Microsoft Dynamics CRM then uses these values to set the Windows Workflow Foundation dependency properties.
The following is an excerpt from the Windows Workflow Foundation reference documentation describing the use of dependency properties:
In Windows Workflow Foundation, dependency properties support three use cases. First, if an instance property of an activity is implemented by using a dependency property, that property can be assigned an ActivityBind instead of an actual value. Second, activity properties that are metadata (that is, the value cannot change at run time) should be implemented by using dependency properties, specifying the Metadata option. Third, dependency properties support attached properties, which are properties that are applied to dependency objects dynamically.
