5 New Features in C# 9 (not including Records)

Video Description

C# 9 is out and there are a bunch of new features. But do we really need them? Just because they are new does not make them valuable. In this video, we will look at five new features. We will identify how to use each and then talk about where they are useful (as well as where they are not useful). We won't be covering records because they deserve their own video, which comes out in a couple of days.
