Aspose.cad 18.8.0 unable to read dwf file in .net core project


Hi Support,

I downloaded the last version of Aspose.Cad 18.8.0 in .net core console project and I am trying to load a dwf file with code below and I get an Aspose.CAD.CadExceptions.ImageLoadException Unable to read Dwf Content Exception:

string path = @"D:\AutoCAD POC\DWF\blocks_and_tables.dwf";
        string destination = string.Format(@"D:\AutoCAD POC\DWF\Images\image{0}.png", DateTime.Now.Ticks);
        using (Aspose.CAD.Image cadImage = Aspose.CAD.Image.Load(path))
                cadImage.Save(destination, new PngOptions
                    ColorType = PngColorType.TruecolorWithAlpha,
                    VectorRasterizationOptions = new CadRasterizationOptions
                        AutomaticLayoutsScaling = true,
                        BackgroundColor = Aspose.CAD.Color.FromArgb(0, 255, 255, 255)
                    ResolutionSettings = new ResolutionSetting(1200, 1200)
            catch (Exception ex)

Also I downloaded Microsoft.Windows.Compatibility(2.0.1) to avoid issues in the Run-time due that using this approach I can use this library to read dxf and dwg file extension in .net core console project/net standard.
Now testing with the same code in .net framework project (4.7.0) the library works as expected.

Do you know what can I do to fix the Error “Aspose.CAD.CadExceptions.ImageLoadException Unable to read Dwf Content Exception” in .net core console project in order to read a dwf file.?
thanks for your support and have a good day.
