Question

I have a class that I am binding to my view model. It is basically a struct full of displayable strings for the UI:

class DisplayVO
{
    public string Title { get; set; }
    public string Description { get; set; }
    // ... about a dozen more properties 
}

Basically the DisplayVO wraps a bunch of properties that are bound to the UI. This works until one portion of the UI modifies a property (e.g. the user can edit the Description) so I want to update the UI with the new modifications.

So what I would normally do is implement the INotifyPropertyChanged interface and override each set method to broadcast PropertyChanged(this, new PropertyChangedEventArgs(info));

I’m feeling lazy – is there a way to have this done for all members of the class? In Flex I could do:

[Bindable]
public class DisplayVO
{
    private var Title:String;
    private var Description:String;
}

and magically all of the properties of DisplayVO would be wrapped to automatically broadcast changes without me having to write all of the boilerplate. Is there an equivalent for C# and WPF?
