System Information:

Describe the bug I am unable to use this library when my project is built with .Net 4.7.2. The same code is working for .net7.0-windows v7.0.15

To Reproduce Steps to reproduce the behavior:

  1. Create a project then call MLContext.AnomalyDetection.DetectSeasonality
  2. See error: The type initializer for 'Microsoft.ML.Transforms.TimeSeries.FftUtils' threw an exception. Inner exception: BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

Expected behavior The function should not throw an exception.

Sample Snipet

            var mlContext = new MLContext();

            var dataView = mlContext.Data.LoadFromTextFile<DataModel>(path: i, hasHeader: true, separatorChar: ',');

            string inputColumnName = nameof(DataModel.value);

            int period = mlContext.AnomalyDetection.DetectSeasonality(dataView, inputColumnName);
