I used to use something like this:

{{{#!highlight csharp

public int test {
    get
    {
        return _test;
    }
    set
    {
        _test = value;
        OnPropertyChanged();
    }
}

//...

protected void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
    if (PropertyChange != null)
    {
        PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
}
}}}

And before that we just passed in the name. It was kind of a pain.

Implementing INotifyPropertyChanged

It's changed a lot over the years. Here is the latest iteration that I use.

   1 private BindingList<string> _Area = new BindingList<string>();

  13 {
  14     field = value;
  15     PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
  16 }
