Microsoft.ML.Data.ApiUtils.GeneratePeek is not .NET native compiler compatible

[Braysoft]

Windows 10 ML.NET 2.0.1 but applies to all including latest prerelease. NET nuget 2.0.3 Visual Studio 2022 latest.

User code mlContext.Data.LoadFromInumerable() causes: Microsoft.ML.Data.ApiUtils.GeneratePeek uses JIT on release so a release build that uses this will never work with NET native compiler and can not be used on the Microsoft Store rendering any project (such as mine) useless without a workaround.

To Reproduce Steps to reproduce the behavior: 1.Create a blank UWP project 2.Add the following code where it does not already exist:

    public MainPage()
    {
        this.InitializeComponent();
        MLContext mlContext=new MLContext();

        IDataView emptyDv = mlContext.Data.LoadFromEnumerable(new OnnxInput[] { });

    }
}
public class OnnxInput
{
    [VectorType(1 * 24 * 1)]
    [ColumnName("lambda_input")]
    public float[] Open { get; set; }
}

3.build in release mode with .NET native compiler (or debug with .NET native compiler checked and F5) 4.run app(ctrl+F5 release mode) or F5

Expected behavior App will run and then exit/fail. Inserting Dynamic into the default.rd.xml has no effect due to the JIT nature of the GeneratePeek using il.emit? as mentioned below that is fundamentally incompatible with NET native compiler. I have had frequent communications with someone from NET native at microsoft who has confirmed this issue.
