How to open a “new window” in a Windows 10 Universal App

I had to dig a little bit to find this. Since not all form factors support multiple windows and tablet mode generally discourages floating windows this is probably buried for a reason, but I wanted to do it anyway so here it is:

 var viewId = 0;
 var newView = CoreApplication.CreateNewView();
await newView.Dispatcher.RunAsync(
CoreDispatcherPriority.Normal,
() =>
{
var frame = new Frame();
frame.Navigate(typeof(YourViewPageType), ViewModelDataOrNull);
Window.Current.Content = frame;




viewId = ApplicationView.GetForCurrentView().Id;

ApplicationView.GetForCurrentView().Consolidated += App.ViewConsolidated;

Window.Current.Activate();
});

var viewShown = await ApplicationViewSwitcher.TryShowAsStandaloneAsync(viewId);

Hopefully that will save someone some digging.
