Remarks

For contracts that originate from DefaultJsonTypeInfoResolver or JsonSerializerContext, the value of this property is mapped from JsonRequiredAttribute annotations.

For contracts that use DefaultJsonTypeInfoResolver, the value of this property is also mapped from properties that have the required modifier, unless deserialization uses a constructor that populates all required properties and has SetsRequiredMembersAttribute.

The required keyword is currently not supported in JsonSerializerContext contracts.
