When you use the "Holographic DirectX 11 App" template in Visual Studio, it creates an app that occupies the entire HoloLens view (I believe it's call the Holographic View).
How do you build a Holographic App like the Hologram demos where you can re-size the box and place the app in the Holographic Shell?
BTW, can someone with a higher reputation create a new tag "hololens-directx". I think there are beginning to be more DirectX development and this would help distinguish from the Unity questions.
