Remarks
The TryValidateProperty method tests each ValidationAttribute attribute associated with the property that is identified by the validationContext parameter.
If validationResults is nulla null reference (Nothing in Visual Basic), the method stops at the first validation failure. If validationResults is not nulla null reference (Nothing in Visual Basic), the method evaluates all validation attributes and adds all of the failures to validationResults.
