WPF MVVM Сохранить изменения DataGrid в базу данных

всем. Подскажите пожалуйста как мне сохранить изменения, которые происходят в DataGrid, в базу данных. Использую EF. ПО подходу у меня DataBaseFirst. Так же я изучаю еще mvvm, поэтому если будет возможность распишите поподробнее. Для отображения в DataGrid я использую ObservableCollection<>, я так же понимаю что нужно подписаться на событие CollectionChanged. Но не понимаю как это сделать. Model, ViewModel, View прикладываю.

Model: InfoDrill

public partial class InfoDrill
{
    public int Uid { get; set; }

    /// <summary>
    /// № скважины
    /// </summary>
    public string? HoleId { get; set; }

    /// <summary>
    /// Тип выработки
    /// </summary>
    public int? TypeLcode { get; set; }

    /// <summary>
    /// Название участка
    /// </summary>
    public int? PlaceSite { get; set; }

    /// <summary>
    /// Номер ПЛ
    /// </summary>
    public double? Profile { get; set; }

    /// <summary>
    /// Долгота
    /// </summary>
    public double? Easting { get; set; }

    /// <summary>
    /// Широта
    /// </summary>
    public double? Northing { get; set; }

    /// <summary>
    /// Абс. отм.
    /// </summary>
    public double? Elevation { get; set; }

    /// <summary>
    /// Диаметр бурения, мм
    /// </summary>
    public double? Diam { get; set; }

    /// <summary>
    /// Азимут ист., °
    /// </summary>
    public double? Azimuth { get; set; }

    /// <summary>
    /// Угол наклона от горизонта, °
    /// </summary>
    public double? Dip { get; set; }

    /// <summary>
    /// Глубина скважины,м
    /// </summary>
    public double? Depth { get; set; }

    /// <summary>
    /// Уровень ПВ, м
    /// </summary>
    public double? Uroven { get; set; }

    /// <summary>
    /// Абс. отм. уровня, м
    /// 
    /// </summary>
    public double? UrAbs { get; set; }

    /// <summary>
    /// Начало бурения
    /// </summary>
    public DateOnly? StartDate { get; set; }

    /// <summary>
    /// Окончание бурения
    /// </summary>
    public DateOnly? EndDate { get; set; }

    /// <summary>
    /// Геолог
    /// </summary>
    public int? Geolog { get; set; }

    /// <summary>
    /// Примечания
    /// </summary>
    public string? NotesCommentsText { get; set; }

    public int Project { get; set; }

    public virtual Person? GeologNavigation { get; set; }

    public virtual Place? PlaceSiteNavigation { get; set; }

    public virtual Project ProjectNavigation { get; set; } = null!;

    public virtual ICollection<Rock> Rocks { get; set; } = new List<Rock>();

    public virtual Mine? TypeLcodeNavigation { get; set; }
}

Данный класс мне создался автоматом, когда подключался к БД PostgreSQL

ViewModel

internal class Info_DrilModel : ViewModelBase
    {
        private NavigationManager navigationManager;
        private AnzasContext dbcontext;

        public ObservableCollection<InfoDrill> InfoDrills
        {
            set => Set(ref _infodrill, value);
        }

        /// <summary>
        /// Выбранный элемент скважин
        /// </summary>
        private InfoDrill? _selectedInfodril;
        public InfoDrill? Selected_InfoDrill
        {
            get => _selectedInfodril;
            set => Set(ref _selectedInfodril, value);
        }
 public Info_DrilModel(NavigationManager navigationManager, AnzasContext db)
        {
            this.navigationManager = navigationManager;
            this.dbcontext = db;
        
            InfoDrills = new ObservableCollection<InfoDrill>();
           
            InfoDrills = dbcontext.InfoDrills
                .Include(p => p.PlaceSiteNavigation)
                .Include(item => item.TypeLcodeNavigation)
                .Include(item => item.GeologNavigation)
                .AsNoTracking().ToObservableCollection();

           
           
        }
}
