Send a empty Message or Notification with MVVM toolkit light

Question

I\'m using the MVVM Light Toolkit. I could not find any Ctor of Messenger or Notification class to send a empty message.

ViewModel1:

 private int _select

I don't think that it is possible and frankly I don't see the point of having that kind of message. You could just as well send a string "SelectedWeeklyRotation". It seems strange to have an empty message that has some kind of meaning as you increase the number of broadcast messages - and receivers in your application.

In the version of MVVM Light that I'm using it is not even possible to send an empty message.

However I did see a method in the ViewModelBase that is :

// Update bindings and broadcast change using GalaSoft.MvvmLight.Messenging
RaisePropertyChanged(MyPropertyPropertyName, oldValue, value, true);

This might be of interest for you.
