Unable to build C# API for OpenVINO Execution Provider With VS2019

Describe the bug
Following the instructions at the following URL fails in ways I'll describe in more detail further down: https://github.com/microsoft/onnxruntime/blob/master/docs/execution_providers/OpenVINO-ExecutionProvider.md#csharp-api

Urgency
I want to do inference on the Integrated Intel GPU from C#

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10
• ONNX Runtime installed from (source or binary): Source
• ONNX Runtime version: 1.4.0
• Python version: 3.6.5
• Visual Studio version (if applicable): 2019
• GCC/Compiler version (if compiling from source):
• CUDA/cuDNN version: None
• GPU model and memory:

To Reproduce

• Using cmake 3.14.0
• Visual Studio 2019

git clone --recursive https://github.com/Microsoft/onnxruntime
cd onnxruntime

.\build.bat --config Debug --build --use_openvino GPU_FP16 --cmake_generator "Visual Studio 16 2019" --build_csharp

yields

Error: C:/Users/josh/projects/onnxruntime/build/Windows/Debug is not a directory

Following the baseline CPU build instructions at https://github.com/microsoft/onnxruntime/blob/master/BUILD.md#windows I changed this to

.\build.bat --config RelWithDebInfo --build --use_openvino GPU_FP16 --cmake_generator "Visual Studio 16 2019" --build_csharp

which worked. Following the next line in the OpenVino instructions, I did:

msbuild csharp\OnnxRuntime.CSharp.proj /p:OrtPackageId=Microsoft.ML.OnnxRuntime.Openvino /p:Configuration=Debug /t:CreatePackage

which gave the following error:

FileNotFoundError: [Errno 2] No such file or directory: 'c:\\Users\\josh\\projects\\onnxruntime\\build\\Windows\\Debug\\Debug\\NativeNuget.nuspec'

I then changed this to

msbuild csharp\OnnxRuntime.CSharp.proj /p:OrtPackageId=Microsoft.ML.OnnxRuntime.Openvino /p:Configuration=RelWithDebInfo /t:CreatePackage

which gave the following error:

C:\Program Files\dotnet\sdk\3.1.401\Sdks\NuGet.Build.Tasks.Pack\build\NuGet.Build.Tasks.Pack.targets(198,5): error NU5026: The file 'c:\Users\josh\projects\onnxruntime\csharp\src\Microso
ft.ML.OnnxRuntime\bin\RelWithDebInfo\netstandard1.1\Microsoft.ML.OnnxRuntime.dll' to be packed was not found on disk. [c:\Users\josh\projects\onnxruntime\csharp\src\Microsoft.ML.OnnxRunt
ime\Microsoft.ML.OnnxRuntime.csproj

and that's where I'm stuck.

Expected behavior
Creation of a Nuget package.
