How have you successfully implemented MessageBox.Show() functionality in MVVM?

Question

I\'ve got a WPF application which calls MessageBox.Show() way back in the ViewModel (to check if the user really wants to delete). This actually works

Answer 1

What about raising an Event like "MessageBoxRequested" handled in the codebehind of the View (anyway it's View only code so I don't see any problem with having this code on the codebehind).
