The top 10 best new features in C# version 6 to 9
summary
A concise run‑down of the top 10 C# 6–9 changes with concrete effects: string interpolation replaces messy concatenation; out var and inline deconstruction remove predeclared temporaries; default interface methods let interfaces ship a fallback implementation; discards use _ and combine with throw expressions; null‑conditional ?., null‑coalescing assignment ??= and nullable reference types (enable in the csproj; compile‑time warnings) tighten null handling; named/value tuples and pattern matching + switch expressions simplify multi‑value returns; record types generate immutable classes, equality and with‑expressions automatically.
