Packaging and Sideload
I have tried to package the Origami project in the tutorial Holograms 101e and sideload the app from Windows Device Portal but failed...
I followed the steps described on this page: Packaging Universal Windows apps for Windows 10.
After building the Origami project in Unity, there are 3 projects in solution "Origami" when opened in Visual Studio. Only the "Origami(Universal Windows)" one has the "Store" option, so I clicked on it.
In the "Create an App package" section, for step 3, I chose "No", since I'm not going to publish the app to the Windows Store.
And in the same section, step 6, I unchecked x64 and ARM because if they are checked, when creating the package it will ask for these files: Origami\App\Origami\Plugins\x64\AudioPluginMsHRTF.dll and Origami\App\Origami\Plugins\ARM\AudioPluginMsHRTF.dll, while I only have Origami\App\Origami\Plugins\X86 directory(after build the project in Unity).
Then I clicked "create", it generated a file called: Origami_18.104.22.168_x86.appxsym.
After the package was generated, I tried to install it in the Windows Device Portal, it gave this error:
Failure reason: Failed to start deployment. Failure text: Package could not be opened. (0x80073cf0)
Did I miss anything? What is the correct way to package an application for HoloLens?
