How to declare an Optional type in C#?

Question

Java 8 has Optional<T> which is nice way to declare optional types as described here. Is there an equivalent way to that in C# ?

@JeroenVannevel: Nullable types work only for value types, as far as I know — AymenDaoudi, Jun 15 '14 at 17:12
For reference types you could possibly use code contracts as per this article http://blog.coverity.com/2013/11/20/c-non-nullable-reference-types/#.U53fXy29KSM — Daniel Dutton, Jun 15 '14 at 18:05
Since C# 8.0 there are [nullable reference types](https://learn.microsoft.com/en-us/dotnet/csharp/nullable-references). — Ruben9922, Oct 23 '19 at 10:53
