What's new in C#? Exciting new features in C# 8.0, 9.0 and 10!

on YouTube ↗01h 03m

" summary

Covers concrete language changes across C# 8–10 with demos: nullable reference types and null-state static analysis produce compiler warnings that can be escalated; async streams (IAsyncEnumerable + await foreach) read files line-by-line with yield and using declarations; pattern matching expands with property/positional/relational patterns; record types introduce init-only props, with copies and value-based equality; shows default interface implementations caveat and how C# versions map to .NET releases. Useful if code-level examples and compiler behavior matter.
