Problems with Aspose.Cells 18.9 nuget

We have found what we believe 2 problems with the Aspose.Cells version 18.9.0 nuget for .NET.

  1. The first problem is that Aspose.Cells for .NET Core doesn’t have a property PdfSaveOptions.ImageType. It exists in the documentation here: https://reference.aspose.com/net/cells/aspose.cells/pdfsaveoptions/properties/imagetype and it exists in the .NET Framework version, but in .NET Core it is marked as internal. We are trying to migrate from .NET Framework to .NET Core and need this property available. Please mark it as public in .NET Core.

  2. The second problem is with the nuget itself. The latest version 18.9.0 exhibits a problem that 18.8.0 does not. The nuget for 18.8.0 has a subfolder “lib\netstandard2.0” and this works fine in visual studio. The latest version 18.9.0 does NOT have this subfolder and visual studio fails to reference it from a project. Instead it has a folder “lib\netstandard20_AuthcodeSigned”. Is this a problem with the packaging of the nuget? The zip file from https://downloads.aspose.com/cells/net does not show this problem.
