Goodbye controllers, hello Minimal APIs

on YouTube ↗54m

" summary

Minimal APIs use C# 9/10 features like top-level statements and implicit usings plus inferred lambda types and attributes on lambdas to remove MVC boilerplate. A working REST CRUD for Customers is built with minimal APIs, Swagger docs, DI, FluentValidation and the third‑party FastEndpoints library, and it performs faster than controllers. Recommended for demos, POCs and microservices (services under ~1,500 lines); not ideal for very large enterprise monoliths. Microsoft predicts 40–80% of new use cases may adopt them.
