" summary

C# 12 ships in November and the preview already exposes concrete features: you can put primary constructors on classes with capture so constructor parameters can be captured into generated fields and used by methods; collection expressions with a factory-attribute and spread let the compiler build arrays, lists or optimized immutable collections from bracket literals; a proposal for optional auto-property bodies referencing a synthetic field surfaces a breaking-change strategy that emits fixes/warnings when upgrading language versions; Roslyn and lang version preview enable trying these now.
