This question is going to be rather short and quick to answer.
I am doing a project using MVVM design pattern in View-First approach. I'm currently using my own implementation for almost everything but I don't wanna reinvent the wheel when it comes to create a Messaging feature to make my ViewModels able to communicate data. So is there a Messaging Framework just like the one implemented in MVVM Light? Cause I'd like not to import the whole framework only for one class.
Another accepted solution would be if there was a way in MVVM View-First to make a dialog and get its ViewModel's values
