Validation Aspect

ValidationAspects have special status and usage. When created with DevArchitecture Code Generator, it comes with a ready method marked NotEmpty(), which contains all the properties for the Create and Update Commands under the Business -> Handlers -> 'ClassName' -> ValidationRules folder of the relevant class.

Changes required for validation must be made within this class. This class uses the FluentValidation library. It takes Command or Query objects in the AbstractValidator under the Business -> Handlers 'ClassName' folder. A separate validation can be written for each of the CRUD operations or for a special case.

ValidationAspects are used as Attributes on Handle methods in Business -> Handlers -> 'ClassName' Command and Query classes.

Usage is as follows. It takes the methods contained in the ClassNameValidator.cs class. The Priority property is used to specify the order in which aspects work on methods.

NOTE: No business code that will directly affect the data and/or database should be written in this class. This class should be used for validation of values from Front-end.
