Reference types are always nullable in C#

In C#8 they added a feature called "Nullable reference type" to warn you when you don't check for null your variables

However, you can achieve similar null-safety warnings on other versions of C# by using a extension for VisualStudio called ReSharper (it's not free)

Details on how it deals with null-checking you can find here
