Data will be removed if I rebuild app to Hololens.

Unity Engine
1

I saved my data by PlayerPrefs of Unity. But when I rebuild app to Hololens, this data was removed. WorldAnchor datas were also removed.

I build app by Visual Studio 2015.
when Build Debug, x86, to Device → datas were removed.
when Build Release, x86, to Device → datas were still removed.

so now, What should I do to fix it?
Thank you!

When you deploy from Visual Studio you are installing a new version/ fresh build of the app, the old version gets removed during this process.

thank you!
So can we build app without Visual Studio?
At Unity Build Setting, ‘Build_and_Run_on’, there are only Local Machine, Windows Phone (cannot build), Local Machine and Windows Phone (cannot build). If I select Local Machine, app will run on Hololens Emulator :frowning:

Visual Studio has a setting on whether it should wipe all data. It’s in project properties under “debugging”, and is called something like “Uninstall application package on every deploy” or something like that.

Thank you.
On Debug Properties, I unchecked “Uninstall and then re-install my package…” .
with target is Hololens Emulator, this bug was fixed.
But with target is Device (real Hololens), when I deployed to Device, application was removed, then re-installed, and datas were deleted.
I checked Device setting (for developers), but It has no build setting (or data setting) :frowning:

Is there anything new on this issue? I have been looking for a solution for this problem for a long time.
