C# 8 and Beyond

" summary

Demonstrations use Visual Studio 2019 previews and Roslyn preview compilers from GitHub and show working examples for tuples, deconstruction, switch expressions, ranges/indices, and pattern matching (including recursive patterns); nullable reference types appear as IDE warnings unless enabled and require annotation to eliminate nullability warnings; async streams and default interface implementations are proposed and sketched; record types, new object initializers, and other conveniences are described — some examples compile live, others are shown only on slides.
