Wrong image width and height when read it with C#-CodePudding

I've got a strange problem. There is an

We need to keep in mind dimensions of this picture: Width is 3000px and Height is 4000px. It looks correct because image is portret.

Then lets try to read it with C#:

private static void TestImage()
{
    using (FileStream file1 = new FileStream("DSC_2446.JPG", FileMode.Open))
    {                
        Console.WriteLine("DSC_2446.JPG :");
        using (var img1 = System.Drawing.Image.FromStream(file1))
        {
            Console.WriteLine($" Width = {img1.Width}");
            Console.WriteLine($" Height = {img1.Height}");
        } 
    }                

    Console.Read();
}

And in results we see some magic!!!

So I've got completely wrong values. Values are switched between properties. Does someone know why it can happens and how to detect/fix this behavior?
