## What it is
A NuGet-distributed ASP.NET Core solution template implementing Clean Architecture (also known as hexagonal, ports-and-adapters, or onion architecture) with domain-driven design principles. It provides a proven starting point for structuring loosely-coupled, dependency-inverted .NET web applications.

## Use cases
- scaffold a new asp.net core project with clean architecture
- start a dotnet web api using domain-driven design
- learn clean architecture with a reference implementation
- structure a loosely coupled dependency-inverted c# codebase
- bootstrap a hexagonal architecture solution in .net
- template for onion architecture in asp.net core

## When to choose
- starting a new ASP.NET Core application and wanting a battle-tested layered structure
- applying DDD and dependency inversion in a .NET codebase
- learning or teaching Clean Architecture patterns with real code

## When to avoid
- building small scripts or microservices where full layered architecture is overkill
- working outside the .NET/ASP.NET Core ecosystem
- needing a runtime framework rather than a project template

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, boilerplate, developer-tools
- domain: web-development, backend, developer-tools, tutorials
- platform: dotnet, cross-platform
- tags: clean-architecture, solution-template, domain-driven-design, ddd, aspnet-core, onion-architecture, nuget-template, project-scaffolding, web-server
