Error : Unable to load DLL 'libgmp-10.dll' when testing azure function c# .net 5.0

I published my c# .NET 5.0 code to azure functions (windows) and im getting this weird error message:
2021-06-21T01:56:53.465 [Error] Executed 'Function1' (Failed, Id=fdefdbba-49a7-44ad-8082-841d2941d90b, Duration=169ms)Unable to load DLL 'libgmp-10.dll' or one of its dependencies: The specified module could not be found. (0x8007007E)
I tried to see the \wwwroot files on the azure functions console but then i get this error:
3 [main] ls (8392) C:\Program Files\Git\usr\bin\ls.exe: *** fatal error - Couldn't set directory to \\?\PIPE\ temporarily.
Any hints?

It seems that the deployment is not done correctly.
Libgmp-10.dll a DLL (Dynamic Link Library) file which is referred to
essential system files of the Windows OS. It usually contains a set of
procedures and driver functions, which may be applied by Windows.
Please delete the Azure Function and, re-create and deploy a fresh code using Develop and publish .NET 5 functions using Azure Functions OR if you are using ADO, Setting up a CI/CD pipeline for Azure Functions.
Let me know if you have any follow up questions.

VR application (Unity with TrinusVR lib) Windows build: Connection reset

I am developing a VR application using Unity 2018.2.8f1 and the TrinusVR lib (a framework that does serverside rendering). When I press play in the editor or build for Linux it works as expected. However, when using the Windows build, only about one frame gets transmitted to the client, then the connection is reset. On the client it shows the errors:
Error streaming video error: java.net.SocketException: Connection reset
Error Error delivering sensor data: java.net.SocketException: Connection reset
Digging into into the logs of the server it seems that this reset is caused by a null reference exception:
Disconnected (Reason: ERROR:ERR_IMG_PROC:Could not deliver frame to client.
System.TypeInitializationException: The type initializer for 'ManagedToNativeWrapper' threw an exception. --->
System.NullReferenceException: Object reference not set to an instance of an object
at System.Drawing.ComIStreamMarshaler+ManagedToNativeWrapper..cctor () [0x00049] in :0`
Does somebody know, what is wrong here? Has anybody seen this problem before?
You can find the complete log files (Windows 10 server and android 7 client) here:

Thank you

Turns out that it actually is a problem of the .NET version on Windows as the trinus lib is made for an older version. Setting the right parameters in Edit > Project Settings > Player, section Other Settings, resolves:
Scripting Runtime Version: .NET 3.5 Equivalent
Api Compatibility Level: .NET 2.0

Is it possible to run Kinect V2 inside a Docker container?

I'm exploring the feasibility of running a C# Kinect Visual Gesture Program (something like Continuous Gesture Basics project https://github.com/angelaHillier/ContinuousGestureBasics-WPF) inside of a Docker for Windows container.
Is this even theoretically possible (run C# Kinect in a Docker for Windows container?)
If the answer to 1 is yes, here are some extra details:
I'm using the microsoft/dotnet-framework:4.7 image as a basis and my initial Dockerfile looks like this:
FROM microsoft/dotnet-framework:4.7
ADD . /home/gesture
WORKDIR /home/gesture
Build the image:
$ docker build -t kinect .
Turn on container:
$ docker run -dit --name kinectContainer kinect
Attach to a powershell session to monkey around:
$ docker exec -it kinectContainer powershell
When I attempt to run my gesture application from the Docker container I get the following error (which is expected since no Kinect SDK was installed in the container):
Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'Microsoft.Kinect, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependenc
ies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058) ---> System.BadImageFormatExcep
tion: Cannot load a reference assembly for execution. erable program. Check the spelling of the name, or if a path was included, verify that the path
--- End of inner exception stack trace ---
at GestureDetector.GestureDetectorApp..ctor()
At this point, the big question is how to install the Kinect v2 SDK [KinectSDK-v2.0_1409-Setup.exe] or the Kinect v2 runtime [KinectRuntime-v2.0_1409-Setup.exe] in the container.
The installers have a EULA and according to some clever University of Wisconsin folks, there is a technique to to extract installers using Wix's dark.exe decompiler(https://social.msdn.microsoft.com/Forums/en-US/a5b04520-e437-48e3-ba22-e2cdb46b4d62/silent-install-installation-instructions?forum=kinectsdk)
ex.
$ & 'C:\Program Files (x86)\WiX Toolset v3.11\bin\dark.exe' C:\installerwork\KinectRuntime-v2.0_1409-Setup.exe -x c:\installerwork\kinect_sdk_installersfiles
The issue I ran into when I got to the underlying msi files is there is no option to run them silently using msiexec.
I've figured out that the runtime installer (Runtime installer (KinectRuntime-x64.msi) extracted from the Kinect v2 SDK) makes at least the following changes in the filesystem:
Creates a folder "Kinect" in C:\Windows\System32 and adds 3 files to System 32:
k4wcll.dll
kinect20.dll
microsoft._kinect.dll
The last three files in System32 should be the 64-bit versions (the installer appears to have x86 and x64 versions of those 3)
Replicating those changes by hand does not lead to success on the host machine let alone in the container.
It's currently unclear what other registry/system changes are occurring with the installer (and whether or not that would get us over the goal line in the Docker container)
Any ideas about how to proceed from here?

In short no. docker on windows does not have the ability to hardware tunnel/map. on Linux, it does via the --device= option
As #VonC has stated you will need to use a Windows VM this could be Hyper-V or you can use Virtual Box then you can provide the Kinect Hardware via the Tunneling method (add/connect device), without this there would be no way for your container be that VM or not to access the hardware of the host machine with windows.

Another approach would be to try and install Kinetic in a Windows server VM, and detect the exact changes brought by said installation.
See for instance "How can I find out what modifications a program’s installer makes?" and a tool like ZSoft Uninstaller 2.5.
Once you have determined exactly what files/registry/variables are impacted by the installation process, you can replicate that in a Dockerfile.

Failed to add a WMAsfReader into the FilterGraph

Add a WMAsfReader caused Error,HRESULT was -2147024770.The code is as follow:
sourceFilter = (IBaseFilter) new WMAsfReader();
((IFileSourceFilter)sourceFilter).Load(fileSource, null);
hr = filterGraph.AddFilter(sourceFilter, "WM ASF Reader");
MessageBox.Show(hr.ToString());
When I run this code on Win10 with WMP,it works well;but it does not work on Win7 without WMP.But I can find the "WM Asf Reader" in the registry,qasf.dll as well.What is the problem?Thanks.

The error code -2147024770 is 0x8007007E ERROR_MOD_NOT_FOUND "The specified module could not be found."
Such error for a Windows core component might indicate that something is broken in your Windows (e.g. certain application installed and registered the same DLL and then it was deinstalled - resulting in broken registration of the original module). It might also be caused by Windows 7 N version having no Windows Media in the default configuration, you are supposed to add the feature by installing a Feature Pack.
but it does not work on Win7 without WMP...
...The Media Feature Pack for Windows 7 N or Windows 7 KN will install Media Player and related technologies on a computer running...
It is not only Windows Media Player missing in N editions, but also the underlying APIs, used by WM ASF Reader.

MdilXapCompile.exe -- Windows Phone Device Deployment Error

I'm trying to deploy my appo to my Lumia 930 so I can test it on something other than an emulator, but every time I hit F5 it basses the build but crashes on deplyment.
MIDLXapCompile log file:
CrossGen failed
Error processing assembly C:\Users\mrrey_000\Dropbox\Dev\Windows Store\AnimeWatcherXYZ EX Summer\AnimeWatcherXYZ.WindowsPhone\obj\ARM\Debug\MSIL\Microsoft.Advertising.Mobile.Display.winmd
Raw error code: 2148733978
I tried deleting the reference to the Microsoft Advertising SDK and applying i oce again, I've also tried to remove the previous version of the app from my device - didn't help.
And yeah, I'm deploying a DEBUG package, not RELEASE.
How can I fix this?
