.NET Project Architectures & Folder Structures — Layered, Clean, Onion, Vertical Slice

How real .NET solutions are organised — solution and project structure, 3-tier and N-layer architecture, Onion, Hexagonal (ports and adapters) and Clean Architecture, Vertical Slice architecture, modular monolith, DDD building blocks, CQRS, the folder structure of each style with naming conventions, shared build settings (Directory.Build.props, central package management), test projects, where cross-cutting concerns live, and how to choose an architecture.
