Using System.Text.Json, I have a class with some properties including System.Drawing.Font properties.

There’s no problem serializing it, but i can’t deserialize it.
I Get the error Deserialization of types without a parameterless constructor

Here is a simplified example :

When i click button1, i serialize the object, but i get the error when i click button2 to deserialize.

using System.Text.Json;
namespace WinFormsApp1;

public partial class Form1 : Form
{
    private CasaSettings _casaSettings;
    private string _stringJson;

    public Form1()
    {
        InitializeComponent();
        _casaSettings = new CasaSettings();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        _casaSettings.DefaultFont = textBox1.Font;
        _stringJson = JsonSerializer.Serialize(_casaSettings, _casaSettings.GetType());
    }

    private void button2_Click(object sender, EventArgs e)
    {
        CasaSettings convertedSetting = (CasaSettings)JsonSerializer.Deserialize(_stringJson, typeof(CasaSettings));
    }
}

public class CasaSettings 
{
    public CasaSettings() { }

    public int AlertIntervalRefresh { get; set; } = 60000;

    public Font DefaultFont { get; set; } = new Font("Tahoma", (float)8.25, GraphicsUnit.Point);
}

I need to continue using System.Text.Json.
I think i need to use a converter but can’t make it work.

Thanks
