Description
Relaxes nullability check for C# 8+ targeting. C# 8 introduced nullable reference types, thereby removing the restriction that only value types can be made nullable.
Related Issue
(#1632)
Motivation and Context
Specifically when using System.Text.Json, the new nullable ignore attribute does not trigger Roslyn warning CS8601, leading to potential runtime null reference exceptions.
Previous Behaviour / Output
Previously, reference types such as
stringwould not include the?nullability indicator.New Behaviour / Output
Now, all C# types (reference and value) will include
?when optional, since the serialized data may contain null values for those properties per the specification.How Has This Been Tested?
Ran before and after examples in a Docker environment.
