**Urgency**
It is blocker for private project

**System information**
- OS Platform and Distribution (e.g., Linux Ubuntu 16.04): L4T
- ONNX Runtime installed from (source or binary): Source
- ONNX Runtime version: 1.6.0 and 1.5.2
- Python version: 3.7
- Visual Studio version (if applicable): Not installed
- GCC/Compiler version (if compiling from source): 7.3.1
- CUDA/cuDNN version: CUDA 10.2, cuDNN 8.0
- GPU model and memory: Integrated

**To Reproduce**
- Clone onnxruntime repository
- Use build.sh script to build onnxruntime:
`./build.sh --config Release --update --build --parallel --build_nuget \
--use_tensorrt --cuda_home /usr/local/cuda --cudnn_home /usr/lib/aarch64-linux-gnu \
--tensorrt_home /usr/lib/aarch64-linux-gnu`
- Using dotnet install nuget package
`dotnet add package Microsoft.ML.OnnxRuntime.Gpu -v 1.5.2-dev-20210113-0851-ad7cc541f -s /home/user/nugetPackageLocation/`

**Expected behavior**
After compilation and installation of nuget package onnxruntime-gpu, it should be possible to run YOLOv5 on C#
