Useful features from C# 7 to & 9 with Julien Couvreur

There are loads of new useful functions in the C# languages, but many of us are focusing on writing code so not all of us have taken the time to try the new features.

We have invited Julien Couvreur to show us useful features from recent versions of C#.
In this meetup, Julien will talk about some of the hidden gems in C# 7 to 9.
He will cover general-purpose features like pattern matching, local functions, async improvements, nullable reference types, default interface members, and tuples.

Bio:
Julien is a longtime C# and .NET explorer turned compiler dev and language designer at Microsoft.
