Notify related Property without call setter

[ahdung]

some times we need notify Property changed manually, for example, notify Total when collection changed, in this case we do not call Total=xxx, just call OnPropertyChanged("Total"), this cause other property that reference Total can't raised, so can you don't generate this:

public string GivenNames
{
public string GivenNames
{
  get => givenNames;
  set
  {
    if (value != givenNames)
    {
      givenNames = value;
      OnPropertyChanged(InternalEventArgsCache.GivenNames);
      OnPropertyChanged(InternalEventArgsCache.FullName);
    }
  }
}

generate this:

public string GivenNames
{
  get => givenNames;
  set
  {
    if (value != givenNames)
    {
      givenNames = value;
      OnPropertyChanged(InternalEventArgsCache.GivenNames);
    }
  }
}

void OnPropertyChanged(PropertyChangedEventArgs eventArgs)
{
  PropertyChanged?.Invoke(this, eventArgs);

  if (eventArgs == InternalEventArgsCache.GivenNames)
    PropertyChanged?.Invoke(this, InternalEventArgsCache.FullName);
}

Just use the DoNoCheckEquality attribute and just assign some dummy value to your master property, that should raise all the events you need.

Sorry, but this would be a major breaking behavioral change, so we can't change that. That would need to be some kind of separate feature.

As a workaround, you could raise OnPropertyChanged("") with an empty string to reevaluate every property (which would be the common approach to this problem), or use [DoNotCheckEquality] and then affect the property value to itself (e.g. GivenNames = GivenNames;) like Tom suggests.
