ONNX Runtime DLL load Error

[rishabhmalhotra027]

While using onnxruntime reference in a net framework project, we are hitting the following exception in production

Unexpected error encountered by 'Alexandria' processor: System.TypeInitializationException: The type initializer for 'Microsoft.Substrate.KnowledgeMining.DefinitionExtraction.PreProcessingHelperFactory' threw an exception. ---> System.TypeInitializationException: The type initializer for 'Microsoft.ML.OnnxRuntime.NativeMethods' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'onnxruntime': The specified module could not be found.

We cannot reproduce the same error in local machine, as the dll reference is present in the project, and we're able to see the dll in the target folder once we build the project.

Here are the references in the dev csproj
<Reference Include="Microsoft.ML.OnnxRuntime">
<HintPath>$(PkgMicrosoft_ML_OnnxRuntime_Managed_1_4_0)\lib\netstandard1.1\Microsoft.ML.OnnxRuntime.dll</HintPath>
</Reference>
<Reference Include="netstandard" />
<Reference Include="System" />
<Reference Include="System.Memory">
<HintPath>$(PkgSystem_Memory)\lib\netstandard2.0\System.Memory.dll</HintPath>
</Reference>

<ItemGroup>
<Content Include="$(PkgMicrosoft_ML_OnnxRuntime_1_4_0)\runtimes\win-x64\native\onnxruntime.dll" Visible="false">
<Link>onnxruntime.dll</Link>
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</Content>
<Content Include="$(PkgMicrosoft_ML_OnnxRuntime_1_4_0)\runtimes\win-x64\native\onnxruntime.lib" Visible="false">

</Content>
</ItemGroup>

The same references had to be mentioned in the test csproj, otherwise the unit tests were hitting an error - Unable to find an entry point named ‘OrtGetApiBase’ in DLL ‘onnxruntime’ in local, and the same exception as above in cloud build. Do we need to add something else in the csproj to make this work in prod?
