What's next in C#
summary
C# 12 ships next week and the session shows live code converting preexisting examples to new features, proving primary constructors on non-records generate constructors and capture parameters when needed, and that collection expressions with [ ] and spreads produce efficient arrays or immutable collections via Roslyn-chosen creation paths and attributes. The demo uses compiler docs and the roslyn repo, shows evaluation order guarantees, suggests future implicit extensions and dictionary syntax, and explains a plan to use analyzers and fixes to safely introduce small breaking changes.
