I have freshly installed Unity 2018.3.10 with Visual Studio 2017 (15.9.10). I cannot deploy a bare-bones 3D unity application to HoloLens due to an error in Visual Studio ("DEP0100: Please ensure that target device has developer mode enabled. Could not obtain a developer license on 127.0.0.1 due to error 80004005"). Here are the steps to reproduce:
Create new 3D scene in Unity. Set camera position to 0,0,0 and camera clear color to solid black. Create a red cube in front of the camera with dimensions 0.1x0.1x0.1
Window / Package Manager : remove Ads, Analytics Library, In App Purchasing, TextMesh Pro, Unity Collaborate, because I don't need these
Build settings and Project Settings (Quality and Player Settings) shown in screenshots. Scripting backend = IL2CPP
Unity successfully generates a .sln file
The HoloLens has OS build 10.0.17763.316 . Under Settings/Update & Security / For developers , I set 'Use developer features'=on, 'Enable Device Portal'=on
I don't know if it's necessary, but on my PC, I also do Settings/Update & Security/For developers, select 'Developer mode', 'Enable Device Portal'=on, 'Device discovery'=on
Connect HoloLens to PC via USB cable
Open the .sln file in Visual Studio. Set to Release, x86, Device. Build / Deploy Solution
Compilation is successful, and Visual Studio asks for a PIN, which I get from the HoloLens by opening Settings / Update & Security / For developers / Device Discover / Pair
Visual Studio shows error message: DEP0100: Please ensure that target device has developer mode enabled. Could not obtain a developer license on 127.0.0.1 due to error 80004005
Make sure Developer mode is enabled on the Hololens. You can find this in settings.
If that doesn't work then...
Try reseting the device.
Reseting is annoying but that is the solution found for 'Could not obtain a developer license on 127.0.0.1 due to error 80004005'on the forums:

"shyykoserhiy ✭ November 2017 I've had the same issue. Tried to run
from two different setups: MacBook Pro 2016 with touch bar (windows 10
Pro in Bootcamp) and Surface Pro 4. Same error on two different
machines. So I've though that it might be a problem with the HoloLens
itself. After Resetting the HoloLens from Settings> Update and
Security> Reset everything started to work just fine. This is the only
solution that've worked for me."
It is also mentioned in the unity forums:

"billyjacobs So I did some searching and found that one way to solve
the problem is to reset your hololens device. It will have the latest
version of the device software after you reset it. I was hesitant
against doing this at first but it worked like a charm."

I'm trying to build a very simple UWP app (for PC Desktop only) with a single image target and camera using Vuforia on Unity.
Everything works fine in the Editor, but after I build and run the app I get the following error on a black screen :
I don't even know where to debug this, as the only log I get is this error and nothing else. I also tried delayed initialization, but this same behavior happens when I manually call VuforiaAppllication.Instance.Initialize(); after it's initialized and before it's started.
Here's my build settings :
I'm using Unity 2020.3.30f1 and Vuforia 10.2.5, the only target SDK installed on my system is 10.0.19041.0 and also, I have Visual Studio 2019 Community installed if that info helps.
Fixed by disabling my laptop's webcam from device manager, and connecting an external USB camera.
I have taken the "default game" (tables and chairs) of Unreal Engine 4.26, and packaged it for the Hololens emulator using these instructions.
I can launch the latest Hololens emulator (10.0.19041.1136) and install the Unreal application, and an icon shows up for it in the apps panel. But when I launch the app, the entire screen is black. When packaging the application for Windows (64 bit), the application works just fine.
What could be the issue? Older versions of Unreal Engine work fine, in particular I have verified that Unreal Engine version 4.25 works with the emulator.
Other perhaps relevant info: Intel Core i7-5960X, Windows 10 version 1909 build 18363.1440, NVIDIA GeForce RTX 2080 Ti, Version 456.71.
I have also used the Unreal 4.26-chaos engine, completely fresh. I choose a blank project from the Games category, C++, Scalable 2D or 3D, raytracing disabled, mobile/tablet with starter content. Then add the Microsoft Windows Mixed reality plugin and the Hololens plugin. In settings I get a signing certificate and define a project name, using Windows SDK version 10.0.18362. Again, no joy. The same thing, just as a Blueprint, not a C++ project, also does not work.
Also checked Hololens emulator version 10.0.19041.1117. No joy.
We followed all the steps exactly per docs including the “run in VR mode setting” in packaging and reproduced this issue today.
So, we are going to recommend to you to file a defect over with UE 4.26 via Unreal Engine Support | Get Help and Customer Service for UE - Unreal Engine. Besides, you can also open a support case via http://aka.ms/hololenssupport for free to discuss further too on anything we can offer for HoloLens 2 emulator/device:
The issue in the Epic's article. You should enable the "start in VR" option in Project > Description > Settings as from
https://learn.microsoft.com/en-gb/windows/mixed-reality/develop/unreal/tutorials/unreal-uxt-ch6
It was added in 4.26.
And we don't support Unreal 4.26-chaos yet. Please take simple 4.26.
I'm new to xamarin. I wrote a simple "Hello World" app using VS 2019 on Windows 10 which runs successfully on the emulators. I have an iMAC on my network and it is successfully connected to my Windows visual studio on Win10 machine. No update warnings or mismatch version error message(s) during the paring of the Windows VS to the remote iMac. On my list of emulators, I have a long list of emulators and "Remote Device" option. All in all, all is well when I work with the emulators.
Now, when I connect my iPhone XR (iOS 13.4.1) using USB to my VS 2019 on Win10, the expected result would be that my device would show up along side of all the emulators so that I can deploy to the device for debugging. My first question is whether or not that is the right assumption. If it is, then in my case that doesn't happen. When I start iTunes program on my Windows machine, it has no issues connecting to my iphone (I can do backup, restore, etc.). Interestingly, in VS, the Device Log has no issues connecting to the connected iphone either. My phone is listed on the drop down box on the top left hand corner of the screen. At this point, I can only assume that is not a connection issue.
What I'm left with is some kind of mismatch setting on VS 2019 in Win10 or on my connected iphone that is causing VS 2019 on win10 not seeing my usb-connected iphone. Any ideas what setting I should fiddle around with? Thanks in advance.
First option, you need to connect iPhone over USB on Mac device , then you can debug in iPhone device .
Second option ,If Mac device not always around you , you also can connect to iPhone device Over Wifi .
An important part of the developer workflow is deploying to a device. Xcode 9 introduced the option of deploying to an iOS device or Apple TV through a network, rather than having to hardwire your devices every time you want to deploy and debug your app. This feature has been introduced in Visual Studio for Mac 7.4 and Visual Studio 15.6 release.
This guide details how to pair and deploy to a device over the network : https://learn.microsoft.com/en-us/xamarin/ios/deploy-test/wireless-deployment?tabs=windows
Ok, so what you need to do is select "Debug|iPhone" or "Release|iPhone" from the build configuration menu.
My setup
HoloLens
Windows 10 October 2018 Update (10.0.17763.134)
Desktop
Windows 10 Enterprise
Visual Studio Community 2017 Version
Unity 2018.2.19f1 (Latest 7th December 2018 Update)
The Problem
I am unable to deploy any application to the HoloLens, but able to deploy it on hololens-emulator. I'm attempting with the Origami application exported from Unity as in the tutorial. I'm able to pair with the HoloLens easily and I have developer mode on. Visual Studio also does auto-detect the device as a remote machine. But when I attempt to deploy it, I always get the same "DEP0100" error, that the device is not in developer mode though the device is already in a developer mode. I'm at a loss for what else to try, or what setting I've missed. I've reset the HoloLens several times and reinstalled Visual Studio only to get the same thing.
I have already tried the solution mentioned here Unable to deploy HoloLens application but it didn't work for me.
It is not clear what you got. But I have couple ideas:
You connected to HL as Remote Machine, but HL is Device.
You built an appx as x64, but HL is x86.
You didn't install a proper runtime, debug or release.
You use older SDK than HL platform version.
You minimal target platform is higher then HL platform version.
Maybe something else. You need to investigate the Hololens logs. Open "Windows Device Portal"/System/Logging.
Then you need to select some providers with severity by choosing them in box and clicking "Enable". I usually begin from "Microsoft-Windows-WinRT-Error" ETW provider.
DO NOT CLOSE THE LOGGING PAGE!!!!!
Start the debugger with app, see the error and go to Logging page. Try to find out the root of issue.
I'm new with unity and hololens and I started to explore it.
I have a macbook (I don't know if it is a problem).
I downloaded Unity with all the components (Vuforia, IL2CPP etc.).
When I change project settings for the hololens development I have some problems.
In particular when I check the box "Virtual Reality Supported" I don't find in the list below the Hololens option.
Also if I click on "+" button. I see: Vuforia, Oculus, OpenVr but not Hololens!
Furthermore also in the field: "scripting backend" i found only "none" and "IL2CPP".
Now, as I already say, i have downloaded all the components during the installation process.
Which is the problem?
Because Hololens runs on UWP, you need Windows. This is because the windows development libraries do not run on mac (or any Unix).
Your only option is to use something like boot camp to install windows 10 on your Mac (fast and works very well), or run a VM (a lot slower, but can be convenient if you develop on the mac and only build in the VM).
Everything should work fine with the exception of the hololens emulator, which does not work on every MacBook hardware.
You have to download the correct tools for Hololens development, here is the link:
