Remarks

Contracts originating from DefaultJsonTypeInfoResolver or JsonSerializerContext, derive the value of this property from nullable reference type annotations, including annotations from attributes such as AllowNullAttribute or DisallowNullAttribute.

This property has no effect on deserialization unless the RespectNullableAnnotations property has been enabled, in which case the serializer will reject any null deserialization results.

If the property has been associated with a deserialization constructor parameter, this setting reflected the nullability annotation of the parameter and not the property setter.
