I tried the examples given on this tutorial and it works fine: https://developer.microsoft.com/en-us/windows/holographic/holograms_240.
After I build the examples using Unity the output is a folder with 2.16 GB size and it is a visual studio project (.sln file). I think the output will be a single file (like apk for Android).
What I need is how to create a Hololens application file from the this Visual Studio project?
I guess this explains what you are after.

For Unity/Hololens, you need to build without C# debugging, then in VS, select Master and x86 and disable ARM and X64 when creating the package.
But I can't confirm this applies to Hololens.
Please see my tutorial which includes information on how to build and deploy to the emulator or HoloLens:

Specifically you should follow these instructions, (but the entire tutorial is likely to be useful for you):
Deploy to HoloLens
In the VS toolbar set the Solution Configuration to Release and the Solution Platform to x86. For Build Target select Remote Device. You will see this configuration screen:
If everything goes well you will see your HoloLens listed as Auto Detected. Simply select it. If not on your HoloLens say “Hey Cortana, What is my IP Address” and enter the address, leaving authentication mode set to Universal. Click Debug, Start Debugging. Your project will build and deploy to the HoloLens, you should see a Unity Logo, followed by nothing because we have not implemented anything. Press Stop in Visual Studio closing the application on your HoloLens.
Deploy to Emulator
In the VS toolbar set the Solution Configuration to Release and the Solution Platform to x86. For Build Target select HoloLens Emulator. Click Debug, Start Debugging. Your project will build and deploy to the HoloLens Emulator, you should see a Unity Logo, followed by nothing because we have not implemented anything. Press Stop in Visual Studio closing the application on the Emulator. To learn more about the emulator visit the Hololens Emulator reference.
