Hi @AMROUN Lysa,
I'm afraid I can't say what the best solution is because it depends on many factors, the most important of which I think is based on your requirement.
As you mentioned, the model format you are using is ONNX, and it also supports C#. If you have already used .NET for development, it will be a good choice to continue to use the existing environment, this will maintain the consistency of the technology stack used.
And in my opinion, they both have a good ecosystem, and the additional libraries or tools you may use will depend on your end purpose.
Best regards,
Xudong Peng
