VS Code C# - System.NotSupportedException: No data is available for encoding 1252

Question

I am trying to use ExcelDataReader to read an .xls file on Ubuntu. I am using VS Code with C#. Here is the code:

var stream = File.Open(filePath, mode: FileMode.Open, access: FileAccess.Read);
var reader = ExcelReaderFactory.CreateReader(stream);

I also tried this:

var reader = ExcelDataReader.ExcelReaderFactory.CreateBinaryReader(stream);

When I run, I am getting the following exception:

Unhandled Exception: System.NotSupportedException: No data is available for encoding 1252. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method. at System.Text.Encoding.GetEncoding(Int32 codepage)

I already installed the libmono-i18n-west4.0-cil (tried also with libmono-i18n4.0-all) as I found out some people recommending this, but the problem persists. Also installed the package System.Text.Encoding.CodePages without success.

Can anyone help to solve this?
