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

I keep this around as a snippet. C# 6 adds some nice syntax for invoking the handler.

// INotifyPropertyChanged

public event PropertyChangedEventHandler PropertyChanged;

private void Set(ref T property, T value, [CallerMemberName] string propertyName = null)
{
    if (EqualityComparer.Default.Equals(property, value) == false)
    {
        property = value;
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
