Validation of user input parameters should also be implemented at the application level. ABP provides an infrastructure that makes it easy to implement validation of input parameters. It is recommended to use a tool like AutoMapper to map the entity to the DTO.Infrastructure Layer (Infrastructure)When warehousing interfaces
