System.Text.Json serialize derived class property from a list

[Anduin2017]

I'm migrating a project from Newtonsoft.Json to System.Text.Json in .NET 5.

I have class:

abstract class Car
{
    public string Name { get; set; } = "Default Car Name";
}

class Tesla : Car
{
    public string TeslaEngineName { get; set; } = "My Tesla Engine";
}

I tried:

var cars = new List<Car> 
{ 
    new Tesla(),
    new Tesla(),
    new Tesla()
};

var json = JsonSerializer.Serialize(cars);

Console.WriteLine(json);

The output is:

[
  {"Name":"Default Car Name"},
  {"Name":"Default Car Name"},
  {"Name":"Default Car Name"}
]

Which lost my property: TeslaEngineName.

So how can I serialize derived an object with all properties?

Thanks!
