Gets or sets a value that indicates whether this instance is enabled for execution and validation.
Assembly: System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

This property is a meta property, which means it cannot be changed at runtime. Meta properties do not change after a property instance is created at runtime, so the property must be set to a literal value at design time.
