Could it make sense to have also an ICanBeInitialized without the generics?

Just a question, if a want to show a view that wants to load data by itself, do I simply use the IExpectViewLoadedCallback callbacks to do that? or it's too late?

My draft idea is to do something similar to what we do for the splash screen. Users can define a UserControl (View + ViewModel) as a Partial and we can hook it up into a view. we could show a dialog, show a non model child window or even a simple overlay "fake" dialog. Being a Partial all the conventions that apply to ViewModel lifecycle will be respected.

I already have an implementation of this behavior for all the "popups" of our application.
I'd change the name ShowMessageView :)

IMHO, Radical should support two different scenarios out-of-the-box: confirmation popup (for example to ask confirmation for a delete command) and a "generic" popup (for example to show details).
In the first case Radical could provide the complete "dev experience"

And we could leverage the UI Composition engine to auto-magically compose a UserControl into the pop-up/dialog/child window.

I like the proposal so 👍

Or something like explained in RadicalFx/Radical.Windows.Presentation#5 MVC binding style.
