Let's revisit the nullability feature introduced in C# 8 and its role in enhancing code reliability and reducing runtime errors caused by null references. The talk covers why null references have been historically problematic, how nullable reference types work, and what benefits and challenges they bring to modern .NET development. We'll look at practical examples, discuss its real-world usefulness, and wrap up by reflecting on whether nullability is an indispensable tool or just another feature.
