Building a Scalable .NET Backend Using Clean Architecture (With Optional Layers) in just an second

If you're building a new .NET backend, Clean Architecture is the best way to keep your code organized, scalable, and future-proof.
🧱 What is Clean Architecture?
It's a way to structure your project into layers:
Domain – core business models
Application – commands, queries, interfaces
Infrastructure – external services (API, logging, etc.)
Persistence – database (EF Core, SQL)
API – controllers
Tests – optional unit/integration tests
⚙️ Script-Based Setup
You can auto-generate this structure using a simple CMD script.
✅ You choose what to include:
Want Infrastructure? Type y
Need Tests? Type n
Want to skip Persistence? Type n




Steps To use:

1. use notepad save below code as setup-architecture.cmd

ENDLOCAL pause

2. save this file in respective folder where u want your project files
3. open cmd at this location and run this script by just type its name only that is setup-architecture.cmd
