Where next, C#?
summary
C# 14 roadmap is tentative but concrete: work surfaces on GitHub (Roslyn and csharplang), many features already in preview behind LangVersion dictionary expressions adopt “last wins” semantics; lambda parameter modifiers, nameof without type args, and null‑conditional assignment are implemented or previewable; auto properties gain a generated backing field accessible via a new field keyword (breaking-change warnings). Big effort targets extension members via an extension-declaration inside static classes (staged rollout), async runtime work for faster awaits, and unions remain exploratory. One and a half engineers are full‑time on extensions.
