C# 7.1, and 7.2: The releases you didn't know you had

on YouTube ↗01h 01m

" summary

C# 7.1 surfaces concrete features you can enable per project: async Main for awaiting in console entry points, default literal to drop verbose default(T), and inferred tuple element names so tuple code keeps meaningful member names. C# 7.2 focuses on performance and memory: in parameters / read-only struct to avoid copies, Span/ref struct and stackalloc for zero-copy buffers, plus non‑trailing named args, leading numeric underscores and private protected accessibility. Language version is project-scoped via CSProj with a light‑bulb prompt to opt in.
