C# 8 and Beyond

on YouTube ↗54m

" summary

C# 8 requires .NET Core 3.0 and the Roslyn preview compiler and shows concrete changes: IAsyncEnumerable await foreach streams lines from disk without allocations, ranges + Span<T> slice without copies, and nullable reference types opt-in emit compiler warnings to find null bugs. Live demos use Visual Studio 2019 preview for tuples, recursive pattern matching and switch expressions, using declarations, static local functions, and async streams; record types, default interface methods and other proposals are described but not all are yet implemented.
