Issue

• What did you do?
  Load model saved by ML.NET, the base model is in ONNX format
• What happened?
  Everytime I load the model, a new onnx model file is created in %temp% folder and it is not deleted after releasing model object or after exiting the application. File path: %temp%\7bf1a39c-b65c-4874-927b-2bacbbf57b15\model.onnx
  I tried to delete the file when the model was predicting but there is no error or exception and the result is the same.
• What did you expect?
  This file should be deleted or better not be created since it exposes our model to the user consumes too much user's memory.
