My VS2015 solution consists of two projects: DataModel and DesktopClient.
DataModel has a Customer class - thats an EntityFramework 6 DB entity. Customer has a FirstName property.
In DesktopClient there is an extended class CustomerExt.
In DesktopClient, is it possible to have a notification to CustomerExt.FirstName changes? Defining a partial Customer across two projects won't work - DataModel is compiled first and it won't have partial properties defined in DesktopClient.

```
public class CustomerExt : Customer, INotifyPropertyChanged
{

    public object Clone()
    {
        return this.MemberwiseClone();
    }

    private bool _isChecked;
    public bool IsChecked
    {
        get { return _isChecked; }
        set
        {
            this._isChecked = value;
            NotifyPropertyChanged("IsChecked");
        }
    }

    #region INotifyPropertyChanged

    public event PropertyChangedEventHandler PropertyChanged;
    private void NotifyPropertyChanged(String info)
    {
        this.PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(info));
    }
}

```
