Problem with Serializable class implementing INotifyPropertyChange

[Joshua Belden]

I have a class that is marked as Serializable that implements
INotifyPropertyChanged.

private event PropertyChangedEventHandler _PropertyChanged;
public event PropertyChangedEventHandler PropertyChanged
{
add { _PropertyChanged += value; }
remove { _PropertyChanged -= value; }
}

When I compile the class, FxCop complains:

"Field _PropertyChanged is a member of type User, which is serializable, but
is of type System.ComponentModel.PropertyChangedEventHandler, which is not
serializable. Add the NonSerializedAttribute to _PropertyChanged."

If I add the NonSerialized attribute to the event declaration...

[NonSerialized()]
private event PropertyChangedEventHandler _PropertyChanged;

It complains:
Attribute 'NonSerialized' is not valid on this declaration type. It is valid
on 'field' declarations only.

Is there any way around this?
