✅ How to edit and save specific appsettings.json (project root) section?

public void SetYear(int year)
        {
            var config = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                .AddEnvironmentVariables()
                .Build()
                .Get<Config>();

            config.ConfigurableYear = year;

            var jsonWriteOptions = new JsonSerializerOptions()
            {
                WriteIndented = true,
                
            };

            var newJson = JsonSerializer.Serialize(config, jsonWriteOptions);

            var appSettingsPath = Path.Combine(Directory.GetCurrentDirectory(), "appsettings.json");
            File.WriteAllText(appSettingsPath, newJson);
            
        }
