The onion architecture, introduced by Jeffrey Palermo, overcomes the issues of the layered architecture with great ease. With Onion Architecture, the game-changer is that the Domain Layer (Entities and Validation Rules that are common to the business case ) is at the Core of the Entire Application. This means higher flexibility and lesser coupling. In this approach, we can see that all the Layers are dependent only on the Core Layers.

If you found this Implementation helpful or used it in your Projects, do give it a star. Thanks!

Overview

We will talk about Onion Architecture In ASP.NET Core and it's advantages. We will also together build a WebApi that follows a variant of Onion Architecture so that we get to see why it is important to implement such an architecture in your upcoming projects.

Here is a list of features and tech we will be using for this setup.

• Onion Architecture
• Entity Framework Core
• .NET Core 3.1 Library / .NET Standard 2.1 Library / ASP.NET Core 3.1 WebApi
• Swagger
• CQRS / Mediator Pattern using MediatR Library
• CRUD Operations
• Inverted Dependencies
• API Versioning

Share it!

I have personally not come across a clean implementation on a WebAPI, which is the reason that I started building this up. There are quite a lot of improvements and fixes along the way from the day I started out. Thanks to the community for the support and suggestions. Please share this Repository within your developer community, if you think that this would a difference! Thanks.

onionarchitecture's Issues

lint: indentation of BaseEntity.cs

just fix the indentation of BaseEntity.cs (just for code style 😄)

MediatR is now superseeded

If you upgrade to latest version, the syntax for AddMediatR has changed:

        services.AddMediatR(cfg => 
                {
                cfg.RegisterServicesFromAssembly(Assembly.GetExecutingAssembly());
                }
        );
