Consider adding SetProperty, using the CallerMemberName attribute, to the ObservableObjectBase

public string Description {
  get { return _description; }
  set { _description = value;
        NotifyPropertyChanged(“Description”);
      }
}

public string Description {
    get { return _description; }
    set { SetProperty(ref _description, value); }
}

protected virtual bool SetProperty<T>(ref T storage, T value [CallerMemberName] string propertyName = null) {

  if (object.Equals((object)storage, (object)value))
    return false;

  storage = value;
  this.NotifyPropertyChanged(propertyName);
  return true;
}
