	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnValidationBeginning	Called when validation begins. (Overrides ValidationMessageObserver.OnValidationBeginning(ValidationContext).)
	OnValidationEnded	Called when validation ends. (Overrides ValidationMessageObserver.OnValidationEnded(ValidationContext).)
	OnValidationMessageAdded	Called when validation messages are added. (Overrides ValidationMessageObserver.OnValidationMessageAdded(ValidationMessage).)
	OnValidationMessageRemoved	Report removed messages to the task list. (Overrides ValidationMessageObserver.OnValidationMessageRemoved(ValidationMessage).)
