Implement a own DialogService?

[hmi95]

I would like to have DialogService with methods like ShowMessageBox or other type of doalogs, which are not fits to scenario with custom dialog window and/or views (and viewmodels). My question is what is the best way to extend implementation of class DialogService : IDialogService provided by the library? And if I write my own implementation, should I register it somehow or just inherit DialogService (if I register it I will have two regietered classes) ?

I could not find an answer to this question. I have nearly the same question. Can I write my own implementation and just inherit DialogService? How can I register it, so it will be "used" instead of the original? Until now I use a extension to the IDialogService, but now I want to replace ShowDialog (not really, i want do do some things before opening the dialog and then call the original ShowDialog)
