Very short summary on some of the nullability in C#.
I like to use | C# Online Compiler | .NET Fiddle (dotnetfiddle.net) because it lets you choose the .Net version.
Let’s see some examples.
Starting with value types.
Add the ? to make the value types nullable and now we can null them all.
Now for reference types.
Now we add #nullable enable (it can also be added to the project with <Nullable>enable</Nullable> (.NET 8)
Add ? like in the value types and now we don’t get that warning anymore:
Of course if you want to use it, instantiate the class.
See the little things to remember article for more regarding nulls.
