Remarks
This abstract class provides methods that occur at events during the validation process, such as [OnValidationBeginning] and [OnValidationEnded].
If you use these methods, a derived class can perform one or more actions at one or more events during the validation process. Examples of these events include when validation starts or ends.
After all the validation methods have been invoked, the user receives the messages that were added or removed during the validation process.
The methods are called in the following order:
