Running ORT in C# Kernel in Dotnet Interactive Polyglot Notebook

[wpalaceJHA]

Has anyone been successful in getting an ONNX model to run in a C# kernel in a polyglot notebook (https://github.com/dotnet/interactive)? The below C# code runs fine from a command line application, but throws an error in dotnet interactive.
