Multi display using UWP in unity

I posted once this, but now it seems I can't find it, so I will posted again.

I need to deploy an application using vuforia for a windows pc, so I notice that vuforia supports UWP on the latest version but I also need that my application display info on two monitors, but when I change to windows store the multi display feature in unity disappears.
So my question is How can I achieve to build an application with two displays using UWP?

On the other post that now I can't find someone suggest that I could use CoreApplication.CreateNewView and pass the texture from a camera, but I haven't resolve how can I achieve this, so if someone has a solution for this please share.
