Overview of concrete C# 8 changes with demos and gotchas: the preview shows nullable reference types as an opt‑in compiler feature that surfaces warnings and forces constructors or question‑mark annotations; switch expressions and expanded pattern matching let the compiler check exhaustiveness (demo refactors multiple ifs into compact patterns); IAsyncEnumerable plus await foreach and async yield return implement async streams without blocking; ranges/indices and span/memory reduce copying; ref returns/ref readonly and default interface implementations are also shown.
