Не работает Binding в UserControl. Использую паттерн MVVM. Создал object свойство CurrentView, с помощью которого хочу менять контролы

Главное Окно:

MainViewModel, где прописываю все команды:

using Core;
using System.Windows;

namespace EveryDayNote.MVVM.ViewModel

    internal class MainViewModel : ObservableObject
    {
        #region Fields

        public object CurrentView
        {

            set
            {
                _currentView = value;
                OnPropertyChanged();
            }
        }

            CloseAppCommand = new RelayCommand(o => { Application.Current.Shutdown(); });

            RegCommand = new RelayCommand(o => { CurrentView = RegViewModel; });

        }
    }
}
