ValidationOptionAttribute Class
Custom attribute that contains ValidationOption information. This class cannot be inherited.
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
This attribute should only be used as dependency property option. Attributes are ignored if declared on a .NET property.
The ValidationOptionAttribute is intended to be used on Meta-properties only. It will be ignored for instance properties. For more information, see Using Activity Properties for more details.
If the ValidationOptionAttribute is not specified, the behavior defaults to ValidationOption.Optional.
