## From README

ABP Single-Layer Application Template Docs: https://abp.io/docs/latest/solution-templates/single-layer-web-application Solution Structure Single project containing everything: Key Differences from Layered | Layered Template | Single-Layer Template | |------------------|----------------------| | DTOs in Application.Contracts | DTOs in Services folder (same project) | | Repository interfaces in Domain | Use generic IRepository directly | | Separate Domain.Shared for constants | Constants in same project | | Multiple module classes | Single module class | File Organization Group related files by feature: Simplified Entity (Still keep invariants) Single-layer templates are structurally simpler, but you may still have real business invariants. For trivial CRUD entities, public setters can be acceptable. For non-trivial business rules, still prefer encapsulation (private setters + methods) to prevent invalid states.
