Layer Responsibilities

Domain Layer

• Pure business logic
• No dependencies on other layers
• Contains entities, value objects, domain events, and domain services

Application Layer

• Coordinates use cases
• Depends on the Domain layer
• Defines interfaces for services and repositories
• Contains DTOs and application-level logic

Infrastructure Layer

• mplements interfaces from Application and Domain layers
• Handles persistence (e.g., EF Core), external APIs, file systems, etc.
• Should not contain business logic

UI Layer

• WPF or other front-end technology
• Implements MVVM pattern
• Talks to Application layer via ViewModels and Services

Dependency Flow

• UI → Infrastructure → Application → Domain
• Infrastructure implements interfaces from Domain/Application
• No layer should depend on Infrastructure Use Dependency Injection to wire everything together, typically in the UI layer's composition root.

Functionality

Shelf Market Management

• Manage Tenants.
• Manage Shelves.
• Manage Shelf Types
• Assign Shelves to Tenants.

EAN‑13 Barcode Generator (Shelf + Price)

• Generate EAN-13 barcodes for products.
• Input Tenant shelf id and price.
