If you're looking to run ONNX Runtime **without ML.NET**, I just released a NuGet package that does exactly that — fully in C#, without any ML.NET dependency.

✔ Built with `Microsoft.ML.OnnxRuntime` and `Microsoft.ML.Tokenizers`.

✔ Works with .NET Framework (via netstandard2.0) and .NET Core 6, 8, 9.

✔ Designed for Arabic Sentiment Analysis, but can be adapted to other ONNX models.

Let me know if it helps or if you want guidance customizing it for other models.
