'nullable' enable – Unlock the Power of C# Nullability — Maarten Balliauw

Summary

The main theme of this tech talk is the introduction of C# nullability into existing codebases. It discusses the common problem of encountering null reference exceptions, exemplified by accessing the `.length` property of a potentially null string. The practical takeaway is to leverage C#'s nullable reference types, including compiler tricks for value types like `DateTime?` and the `HasValue` property, to proactively manage nullability and prevent runtime errors.
