Wpf Mvvm Entity Framework 数据库优先绑定

Question

I'm building an app using Wpf Mvvm Entity Framework database-first. My model is auto generated so I can't put the NotifyPropertyChanged in the entity.. so I rewrite all the stuff in my viewModel witch is ugly..

I don't think I'm clear so a sample of code, won't post everything for more clarity.

The user control

<TextBox Name="tbClientNumber" Text="{Binding ClientNumber,
         UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/> 

The ViewModel class:

public class ClientManagerViewModel : BaseViewModel
{
    public int ClientNumber
    {
        get { return _clientNumber; }
        set
        {
            _clientNumber= value;
            RaisePropertyChanged("ClientNumber");
        }
    }
}

Auto-generated entity:

public partial class Client
{
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
    public Client()
    {
    }

    public int idClient { get; set; }
    public int ClientNumber{ get; set; }
 }

Thank you all in advance

If you don't want to wrap the entity classes, Fody might help you. You can implement INotifyPropertyChanged on a partial class definition. I have not tried yet though.

All classes that implement INotifyPropertyChanged will have notification code injected into property setters.

Actually I usually simply wrap them like you did.
