Editor's note
I kept this issue deliberately mixed, from language and runtime updates to practical app-building pieces. The C# 14 roundup and the Native AOT state-of-the-art post are especially useful if you’re tracking where the platform is headed, while the middleware and HttpClientFactory guides are solid day-to-day references.
