What's New in C# 14 and .NET 10

on YouTube ↗42m

" summary

C# 14 adds instance-style extension properties, unbounded-generic nameof, a setter null-conditional assignment (?.=), field access in property setters, and partial constructors/events — demos compile but AOT breaks reflection-heavy libs like CSV Helper unless publish properties change. .NET 10 surfaces net tool exec and a friendlier add command, flips Datus GC on for small-container workloads, adds numeric string ordering and async ZIP APIs, improves minimal-API validation and server-sent events, and brings EF left/right join and contains translation. file-based apps publish single-file AOT by default.
