Nullable Reference Types - The Good, The Bad, The Ugly

Video Description

Nullable reference types is not new to #dotnet and #csharp anymore. It's been around since C# 8. I see people (including myself) still struggling with this feature. Why? Well, because all tech influencers just say that you SHOULD definitely use nullable reference types, but when you try to do so, you stumble upon a lot of challenges, headaches and pain. And it's because almost nobody is talking about the bad and ugly parts of nullable reference types. This changes with this video, as I'm about to take you to a journey in which we'll discuss the values of nullable reference types, but also the challenges and pain that they bring.
