'IBM437' is not a supported encoding name

I'm having an error of this,

'IBM437' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.
Parameter name: name
at System.Globalization.EncodingTable.internalGetCodePageFromName(String name)
at System.Globalization.EncodingTable.GetCodePageFromName(String name)
at System.Text.Encoding.GetEncoding(String name)
at Ionic.Zip.ZipFile..ctor(String fileName)
at ConnexusDomain.AppBridge.DecompressFile(String zipfilename, String userID)
console-via-logger.js (173,15)

This occur when my code reaches this line of code

ZipFile zip = new ZipFile(Windows.Storage.ApplicationData.Current.LocalFolder.Path + "\\" + zipfilename + ".zip");

I already tried THIS solution. However I'm having an error of this when it reaches the Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

I'm coding with Ionic Framework and bridge some of the functionalities with C# (.Net Core 2.0).

Any ideas? Thanks!
