Onion.architecture.dotnetcore2.0

Onion architecture implementation with dotnet core 2.X

I recommand Visual studio 2017 "Full Rename Project" extention to rename projets to meet your needs : https://marketplace.visualstudio.com/items?itemName=KuanyshNabiyev.FullRenameProject

After projects renaming using Full Name Project extension, you have to change obj/project.assets.json of each project.

Onion Architecture sets a clear dependency rule between layers, making it a more restrictive variant of Layered and Hexagonal Architectures. At the very center of our application sits a domain model, surrounded by domain services and application services. Those 3 layers form the application core – no relevant application logic should reside outside of it and it should be independent of all peripheral concerns like UI or databases (Grzegorz Ziemoński).

Onion.DAL.Entities

• BaseEntity
• Domain Entities

Onion.DAL.Persistance

• Datebase Context
• DBSets
• EntityConfiguration (Fluent API)
• EF Migrations
