Questions about Build of Hololens App

I am Application development beginner.
I made the first application with Unity and built it with Visualstudio.
However, when I built my next application on Hololens, the first app disappeared.
They are scene name, application name, project, different names and files.
How can I prevent existing apps from disappearing when building another application? please tell me.


  • Hi @Asahi_Sakamoto ,
    when I deploy different projects on HoloLens, they all stay. Did you use the "Release" option in Visual Studio or "Debug"?

  • It builds with release option and X86.
    However, despite different projects, only one of the latest remains in Hololens.

  • Maybe try changing either the package name or version number in the player settings in Unity before you build it out.
