Everything You Need to Know About the Latest in C#
summary
Demos run in Visual Studio Preview with language-version preview turned on and show concrete changes shipping in November: C# 14 in November adds left‑side null‑conditional assignment, short‑form lambdas that allow modifiers, and partial members for properties, events and constructors so source generators can declare and implement hooks. Auto‑properties gain a new field keyword for auto-properties to access the compiler‑generated backing field, with warnings for breaking‑name collisions. New extension blocks let you declare extension methods, properties and static members with real receiver/type parameters. Nominal union types compile to a struct wrapper and enable exhaustive pattern matching.
