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.
