Minimal APIs in ASP.NET 6.0

on YouTube ↗54m

" summary

Live demo upgrades a .NET 5 app to .NET 6 and shows concrete C# 10 changes: file-scoped namespaces and global/implicit usings, top‑level statements and the new WebApplication.CreateBuilder. Minimal APIs use app.MapGet/MapPost/MapPut, return typed bodies via Results (e.g. Results.BadRequest), and support DI into handler parameters. Builds a 46‑line microservice that serves JSON, Swagger and health checks, and demonstrates unit and in‑memory integration tests by exposing Program as a public partial for TestServer—no theory, just working code and measurable improvements.
