What's new in C#? Exciting new features in C# 9, 10 and 11!
summary
Covers concrete language changes and live demos in Visual Studio and Roslyn notes: shows nullable reference types behavior (now default in .NET 6), how turning warnings-into-errors forces constructors or property fixes, and that required + init-only finally prevents hidden null bugs. Demonstrates pattern matching evolution to list patterns and deconstructs, target-typed new, and allocation‑free UTF‑8 handling with UTF‑8 string literals and spans for measurable perf gains; previews C# 12 features (primary constructors, interceptors, collection expressions) and toolchain impacts.
