Now you will be able to include the properties of DerivedType1 when serializing a value declared as BaseType by adding [JsonDerivedType(typeof(TDerivedType))] to BaseType for all derived types: Having whitelisted DerivedType1 in this manner, serialization of your model: Do note that only derived types whitelisted via attribute (or through setting JsonTypeInfo.PolymorphismOptions in runtime) can be serialized via this mechanism. JANUARY 1982 Vol. This may be done providing a value for JsonDerivedTypeAttribute.TypeDiscriminator for each derived type: System.Text.Json will add an artificial type discriminator property "$type" indicating the type that was serialized: Having done so, you can now deserialize your data model like so: And the actual, concrete type(s) serialized will be preserved.
