From Prism guidance I can see that proper way should be using Interaction:

Answer 1

That's true it only exists in the Silverlight prism library ,

What you can do is create your own .

CS :

public class OpenPopupWindowAction : TriggerAction
{     
    protected override void Invoke(object parameter)
    {           
        var popup = (ChildWindow)ServiceLocator.Current.GetInstance();
        popup.Owner = PlacementTarget ?? (Window)ServiceLocator.Current.GetInstance();

        popup.DialogResultCommand = PopupDailogResultCommand;
        popup.Show();                      
    }

    public Window PlacementTarget
    {
        get { return (Window)GetValue(PlacementTargetProperty); }
        set { SetValue(PlacementTargetProperty, value); }
    }       

    public static readonly DependencyProperty PlacementTargetProperty =
        DependencyProperty.Register("PlacementTarget", typeof(Window), typeof(OpenPopupWindowAction), new PropertyMetadata(null));


    public ICommand PopupDailogResultCommand    
    {
        get { return (ICommand)GetValue(PopupDailogResultCommandProperty); }
        set { SetValue(PopupDailogResultCommandProperty, value); }
    }

    public static readonly DependencyProperty PopupDailogResultCommandProperty =
        DependencyProperty.Register("PopupDailogResultCommand", typeof(ICommand), typeof(OpenPopupWindowAction), new PropertyMetadata(null));        
}

XAML :

And if you need here is the Code for the DialogWindow it self .

cs:

public partial class ChildWindow : Window, IPopupDialogWindow
{
    public ChildWindow()
    {
        InitializeComponent();
        DataContext = this;
    }

    public new PopupDialogResult DialogResult
    {
        get;
        set;
    }

    public System.Windows.Input.ICommand DialogResultCommand
    {
        get;
        set;
    }
}

xaml :

  


    
        
        
    
    
        This is a child window  launched from the main window
