Question

Iv’e got a Messenger (MVVM Light Toolkit) registered to listen for ViewModelBase
In Iron Python I’d like to send a ViewModel that I got, and box it as a ViewModelBase so that the messenger receives it.
So what is the equivalent to:

var viewmodel = new MyViewModel();
Messenger.Default.Send((ViewModelBase)viewmodel);

in iron python, or is there another work around?

Answer 1

Looking at MVVM Light, it appears that Messenger.Send is generic. If that’s the case (and I’m looking at the right method), then IronPython requires you to explicitly set the type parameters like so:

viewmodel = MyViewModel()
Messenger.Default.Send[ViewModelBase](viewmodel)
