The connected target does not have support for Windows.Storage

I just tried to debug Storage sample and got en error:

12:36:01.444 [NanoDevices: valid device ESP32_REV3 @ COM5]
12:36:01.446 [NanoDevices: Serial device enumeration completed. Found 1 devices]

ESP32 info:

Connected to:
ESP32 (ESP32-D0WD-V3 (revision v3.1))
Features WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Flash size 4MB unknown from TENX (manufacturer 0x94 device 0x16406)
PSRAM: undetermined
Crystal 40MHz
MAC A0:A3:B3:2B:5F:7C

I'm unable to save & load any settings file in internal storage.

That sample seems to be out of date. Most targets including esp32 have moved to https://github.com/nanoframework/System.IO.FileSystem

Even chatGPT || Gemini don't know how to use ESP32 internal storage. Here is the recent snippet:

using System.IO;

private const string configFilePath = "I:\\config.json"; //  I: is internal and \\ is a must

private static void LoadSettings()
{
    try
    {
        if (File.Exists(configFilePath))
        {
            using (var fileStream = new FileStream(configFilePath, FileMode.Open, FileAccess.Read))
            using (var reader = new StreamReader(fileStream))
            {
                string json = reader.ReadToEnd();
                settings = (DeviceSettings)JsonConvert.DeserializeObject(json, typeof(DeviceSettings));
            }
        }
    }
    catch (Exception ex)
    {
        Debug.WriteLine($"Error: {ex.Message}");
    }
}
    private static void SaveSettings()
    {
        try
        {
            using (var fileStream = new FileStream(configFilePath, FileMode.Create, FileAccess.Write))
            using (var writer = new StreamWriter(fileStream))
            {
                string json = JsonConvert.SerializeObject(settings);
                writer.Write(json);
            }
        }
        catch (Exception ex)
        {
            Debug.WriteLine($"Error: {ex.Message}");
        }
    }

@NimeCloud as stated above and at the top of Windows.Storage repo this library has been discontinued and replaced with System.IO.FileSystem.

Since that replacement, no prebuilt firmware for ESP32 has support for Windows.Storage.
