Let’s catch up with C#!

Filip Ekberg’s NDC Copenhagen talk takes you on a whirlwind tour of C# 9 through 13 (with a sneak peek at 14), showing off features designed to make your code safer and more expressive. We dive into nullable reference types, supercharged pattern matching, init-only setters and new() improvements, record types, primary constructors and collection expressions.

By the end, you’ll see how each language tweak slashes boilerplate, shrinks bug counts and helps you focus on real logic—plus a teaser of what’s coming in C# 14!
