Streamlined by removing AutoWireViewModel

[dvorn]

This PR is not intended to be merged. It is here to give an example of how interactivity can be simplified if it does not attempt to use AutoWireViewModel but follow viewmodel-first approach.

See ItemSelection sample.

Actually the definitions of the interfaces are a bit messy (and some members are actually not used in this sample). But streamlining the interfaces will be a breaking change.

Ok now I understand more where this discussion is coming from, was not aware that usage of AutoWireViewModel slipped into the Interactivity QuickStart at some point. I know how to derive from Confirmation or Notification to extend the viewmodel for the presented dialog view - I was involved in the original implementation in Prism 4. Agree we should either remove the use of AutoWireViewModel from the quickstart due to the impedance mismatch, or just add like you did to show both approaches, because it is not that AutoWireViewModel cannot work with InteractionRequest, there are some scenarios where it works fine. It just doesn't if you want the ViewModel to be tied into the lifecycle of the interaction more directly.

Perhaps showing both in the Quickstart would cover all bases there.

In terms of "streamlining the interfaces", would have to see what you are proposing in PRs that show the implementation and the usages.

Actually the problem is not with AutoWireViewModel. In Prism v5 it goes like this:

    public partial class ItemSelectionView : UserControl
    {
        public ItemSelectionView()
        {
            this.DataContext = new ItemSelectionViewModel();
            InitializeComponent();
        }
    }

Thus, it is the problem with original design of quickstart and prism interactivity.

I have changed all the samples and created a more guided approach to the samples.
