This is a starter template for building professional-grade web applications using a software design pattern called Clean Architecture with ASP.NET Core, which is Microsoft's framework for building web applications and APIs. The purpose of Clean Architecture is to organize code in a way that keeps business logic separate from infrastructure concerns like databases and user interfaces, making the application easier to maintain and test over time. The template is installed as a .NET project template, a kind of pre-built scaffolding. With a single command, a developer can generate a complete new project choosing between Angular or React for the front end, and PostgreSQL, SQLite, or SQL Server for the database. The generated project comes fully wired up with a web API back end, a database layer using Entity Framework Core (which lets developers work with databases using C# objects instead of raw SQL), request handling via MediatR, input validation via FluentValidation, automatic object mapping via AutoMapper, and a test suite using NUnit. The project also includes support for .NET Aspire, a toolset that helps developers run and monitor multiple services locally during development, when you start the app, an Aspire dashboard opens automatically showing logs and URLs for all running components. A developer would use this template at the very start of a new enterprise or commercial web application project when they want a well-structured foundation that follows industry best practices without having to set up all these pieces from scratch. The template supports .NET 10 and is written in C# with Angular 21 or React 19 as front-end options.
