issues when building a Windows Store App

Hi all,

I am on Windows 10 64 bits, got a Visual Studio 2015 and Hololens device. I try to run the https://developer.microsoft.com/en-us/windows/holographic/holograms_100 basic example for different Unity versions but got different issues for both:
1. In Unity 5.5.0f3, after building for Windows Store, there a Visual *.sln file but the destination folder is empty and the solution opened in Visual Studio is also empty.

2. In Unity 5.5.2f1, the "windows store" build settings is just the following black screen window.

Has anyone got a clue?
