Remarks
The workflow runtime uses the default implementation of CacheMetadata to ensure correct construction of a workflow as well as to manage runtime relationships and lifetime rules. The default implementation of CacheMetadata examines the public properties of the activity type using the type's TypeDescriptor. These public members are of type Argument, Variable, IEnumerable<System.Activities.Variable>
, Activity, IEnumerable<System.Activities.Activity>
, or ActivityDelegate. You can override this method to customize the building of the activity's run-time description and to provide custom validation logic.
