Two view-models, each for a separate screen, have an ICommand which has same logic: it needs to choose between asking the user to choose from a list of items or choose an item automatically.

How should the two view-models share this common ICommand?

Should I create an ICommand derived class where I put this logic? I don't think so, commands should not have this kind of logic I think. I think I need to use a separate 'thing', but I don't know what that should be.

  • Extract common logic in separate function then use this function inside both commands. – Fabio Oct 7 '17 at 19:11
  • OK. but where does that function live? Which component \ class? – Daniel Oct 7 '17 at 21:49
