A .NET Core 2.1 N-Layered Architecture reference implementation for building Web APIs using Domain-Driven Design principles.
NLayerAppV3 is a reference implementation of a Domain-Driven Design (DDD) N-Layered Architecture built with .NET Core 2.1. It provides a structured, reusable codebase for developers to build scalable Web APIs, specifically demonstrating patterns for banking and blogging contexts. The project solves the problem of implementing complex business domains with clear separation of concerns and maintainable architecture.
Software architects and .NET developers looking to implement DDD and clean architecture patterns in .NET Core Web API projects, particularly those building enterprise applications with complex business logic.
Developers choose NLayerAppV3 because it offers a production-ready, tested reference architecture that demonstrates best practices for DDD and layered architecture in .NET Core, including support for value objects and transaction management, which are often challenging to implement correctly.
Domain Driven Design (DDD) N-LayeredArchitecture with .Net Core 2
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a well-structured separation of concerns across Domain, Application, Infrastructure, and Distributed Services layers, as evidenced by the sixteen-project solution in the README.
Leverages EF Core Complex Types (OwnsOne) for proper DDD value object implementation, which is a key reason for using .NET Core 2.1 as stated in the description.
Includes extensive unit and integration tests using xUnit, Moq, and FluentAssertions across multiple projects, demonstrating a focus on testability.
Implements TransactionScope in the Application Layer to ensure data consistency and integrity, a feature highlighted in the key specifications.
Built on .NET Core 2.1, which is no longer supported, limiting access to modern features, security updates, and compatibility with newer tools.
The README admits missing elements like Docker, security with Identity Server4, and caching, requiring additional development for production-ready deployment.
With sixteen separate projects, the setup can be overwhelming and unnecessarily complex for simpler applications, increasing maintenance effort.
