Option type alternatives in c#

Question

I want to use an Option type in C#.
Are there any good alternatives for an Option type in C# like 'T option in F#, Option[A] in Scala, or Optional<T> in Java 8?

I know that F#'s 'T option can be used in C# like an external library (FSharp.Core), but I think that is... Well, is it preferable to do so? There may be some problems like name conflicts.

I think the short answer is no. The long answer is in the duplicate. — Jodrell, Apr 06 '16 at 11:39
Nothing exists like that currently. There are some "workarounds" but they aren't satisfactory. The best you can do is go over to the Roslyn github and open a feature request https://github.com/dotnet/roslyn Check the Wiki for discussions about future language features https://github.com/dotnet/roslyn/wiki This is where new features are being incubated/discussed/worked on. — , Apr 06 '16 at 11:41

I think you are looking for Nullable types, which are similar to Javas Optional.

No. Nullable types are more like primitive wrapper classes in Java. Not Optional type. – Naetmul Apr 06 '16 at 11:36
Additionaly, they do not work with reference types – Arkadiusz K Apr 06 '16 at 11:36

Totally different concepts, Nullable is intended to make a struct accept null, Option is a design concept to avoid working with null. – Malkaviano May 16 '19 at 12:31
I'm learning C# having experience with Java/Scala. I found this to be the correct answer in a .NET Core 3.1 environment. – Peter L Jul 02 '20 at 20:25
