Why is it actually impossible to load onnxruntime.dll?

Using the tutorial from the developers at Microsoft, I followed the tutorial created at https://learn.microsoft.com/en-us/dotnet/machine-learning/tutorials/object-detection-onnx.
I made sure to install CUDA V10.1.243 and cuDNN 7.6.5 from Nvidia's site.
Yet somehow, even after copying the entire contents of C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin to my project binary's directory at machinelearning-samples\samples\csharp\end-to-end-apps\ObjectDetection-Onnx\OnnxObjectDetectionApp\bin\Debug\netcoreapp3.0, I keep running into the following error while compiling the example program MS provided: Exception thrown: 'System.DllNotFoundException' in System.Private.CoreLib.dll An exception of type 'System.DllNotFoundException' occurred in System.Private.CoreLib.dll but was not handled in user code Unable to load DLL 'onnxruntime' or one of its dependencies: The specified module could not be found. (0x8007007E).
This should make sure they are accessible from the PATH right? I'm also including their original location in NVIDIA GPU Toolkit in the system PATH as well. I am using the latest version of Visual Studio 2019 to load and compile this solution. Is there anyone out there that has been able to run this code successfully, and if so, how?

'System.IO.EndOfStreamException' in JetBrains.ReSharper.TaskRunnerFramework.dll

When trying to run a very basic xunit test in debugging mode my test project throws several exceptions which seems to come from ReSharper.
Exception thrown: 'System.IO.FileNotFoundException' in mscorlib.dll
Could not find file 'C:\Temp\test\TestProjekt\TestProjekt\bin\Debug\TestProjekt.xunit.runner.json'.
Exception thrown: 'System.IO.FileNotFoundException' in mscorlib.dll
Could not find file 'C:\Temp\test\TestProjekt\TestProjekt\bin\Debug\xunit.runner.json'.
Managed Debugging Assistant 'LoadFromContext'
The assembly named 'xunit.runner.utility.net452' was loaded from 'file:///C:/Program Files (x86)/JetBrains/Installations/ReSharperPlatformVs15_0a4dd3ad/xunit.runner.utility.net452.dll' using the LoadFrom context. The use of this context can result in unexpected behavior for serialization, casting and dependency resolution. In almost all cases, it is recommended that the LoadFrom context be avoided. This can be done by installing assemblies in the Global Assembly Cache or in the ApplicationBase directory and using Assembly.Load when explicitly loading assemblies.

What I have tried so far:
Moved Project away from Default Profile Folder to c:\temp...
Starting Visual Studio 2017 with local admin rights
Updating ReSharper to the latest Version currently available (2018.2.1)
Clearing ReSharper Cache
Clean entire solution
Create new empty class library Project and pull in xunit nuget packages afterwards (.NET Framework 4.7.2)
Downgrading solution to .NET Framework 4.7
Reinstall ReSharper and choose "Install for all users" instead of my user only, to ensure there are no left Overs in my Profile...
It seems that the same test project can be debugged without any issue on the Workstation of a Team mate... so there must be something wrong with my Installation.
What am I doing wrong here? Any ideas?

Enabling Just my Code in Visual Studio at least stops this first Chance exceptions from cluttering my Output. So thats Kind of a Workaround...

UWP Xamarin.Forms 'System.IO.FileNotFoundException' occurred in System.Private.Reflection.Core.dll

My UWP app crashes on Xamarin.Forms.Forms.Init(e, assemblies) with
**Exception thrown:
'System.IO.FileNotFoundException' in
System.Private.Reflection.Core.dllFileNotFound_AssemblyNotFound,
clrcompression**
The app don't crash if I uncheck 'System.IO.FileNotFoundException' from Exception settings, but it's not the best solution because if I uncheck this exception I have another problem with Storage API(I can't use the StorageFolder to get files because the execution doesn't return and no exception is thrown).
I don't know if this problem can be releated with the first exception, but
can anyone fix this problem?

The problem was async/await method when I use Storage API, and for System.IO.FileNotFoundException I had to update Visual Studio.

UnityContainer.Resolve crashes when .NET Native tool chain is enabled

We have a Windows 10 UWP app that runs fine under Debug builds and crashes under Release builds. What it is about release builds that makes it crash is that .NET Native tools chain is enabled - disabling that allows the app to run. But that's not a real fix as it needs to run with .NET Native tool chain if you intend to publish to the store.
We use Microsoft.Practices.Unity for DI. Here's an example of how we register some classes:
container.RegisterType<IBoardView, BoardView>();
And then, in our app we resolve it as follows:
container.Resolve<IBoardView>();
It works fine unless I run it with .NET Native, in which case I get the following exception:
An exception of type 'Microsoft.Practices.Unity.ResolutionFailedException' occurred in Microsoft.Practices.Unity.dll but was not handled in user code
Additional information: Resolution of the dependency failed, type = "WindowsUniversal.ViewModels.Interfaces.IBoardViewModel", name = "(none)".
Exception occurred while: while resolving.
And in the output window I get:
Exception thrown: 'System.NullReferenceException' in System.Linq.Expressions.dll
Exception thrown: 'System.NullReferenceException' in Microsoft.Practices.Unity.dll
Exception thrown: 'Microsoft.Practices.Unity.ResolutionFailedException' in Microsoft.Practices.Unity.dll
An exception of type 'Microsoft.Practices.Unity.ResolutionFailedException' occurred in Microsoft.Practices.Unity.dll but was not handled in user code
Additional information: Resolution of the dependency failed, type = "WindowsUniversal.ViewModels.Interfaces.IBoardViewModel", name = "(none)".
Exception occurred while: while resolving.
Exception is: NullReferenceException - Object reference not set to an instance of an object.
At the time of the exception, the container was:
Resolving WindowsUniversal.ViewModels.Interfaces.IBoardViewModel,(none)
All this works under Debug or Release when .NET Native is disabled. Now I know .NET Native has it's limitations, reflection being one of them. I guess I'm asking how to get around this?
Any insights would be greatly appreciated, thanks.

How to download file from SkyDrive on Windows Phone

I am using sample from https://github.com/liveservices/LiveSDK but it isn't working. I managed to run the PhotoSkyOnTheGo project, but after logging in I get 3 exceptions:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.dll
What am I doing wrong or what source code should I use?
