问题 Thanks in advance. I have some Aggregates in the Domain Layer library. Also, some DTO s in a separate library, which is shared between Server and Client side. An Aggregate of an entity is more informative than its DTO . So, in order to convert from DTO to Aggregate , a repository should be accessed by a Dto Assembler . Interfaces of repositories are in Domain Layer . That's why i come to conclusion that DtoAssembler should be a part of DomainLayer . Is this right? 回答1: No, this would be plain
