Implementing INotifyPropertyChanged - does a better way exist?

Question

Microsoft should have implemented something snappy for INotifyPropertyChanged, like in the automatic properties, just specify {get; set; notify;} I

Answer 1

As of .Net 4.5 there is finally an easy way to do this.

.Net 4.5 introduces a new Caller Information Attributes.

private void OnPropertyChanged([CallerMemberName]string caller = null) {
     // make sure only to call this if the value actually changes

     var handler = PropertyChanged;
     if (handler != null) {
        handler(this, new PropertyChangedEventArgs(caller));
     }
}

It's probably a good idea to add a comparer to the function as well.

EqualityComparer.Default.Equals
