JPEG exif properties are being read differently on windows and ubuntu

JPEG exif properties are being read differently on windows and ubuntu. In my case I'm looking for the Orientation tag and I'm only finding it on Windows.

These are the properties read on ubuntu:

[{"Major":1,"Minor":1,"Value":257,"Interoperability":{"TagID":1,"TypeID":3,"Count":1,"Data":"AQE="},"Tag":700001,"IFD":700000,"Name":"JFIFVersion"},{"Value":0,"IsBitField":false,"Interoperability":{"TagID":101,"TypeID":1,"Count":1,"Data":"AA=="},"Tag":700101,"IFD":700000,"Name":"JFIFUnits"},{"Value":1,"Interoperability":{"TagID":102,"TypeID":3,"Count":1,"Data":"AQA="},"Tag":700102,"IFD":700000,"Name":"XDensity"},{"Value":1,"Interoperability":{"TagID":103,"TypeID":3,"Count":1,"Data":"AQA="},"Tag":700103,"IFD":700000,"Name":"YDensity"},{"Value":0,"Interoperability":{"TagID":201,"TypeID":1,"Count":1,"Data":"AA=="},"Tag":700201,"IFD":700000,"Name":"JFIFXThumbnail"},{"Value":0,"Interoperability":{"TagID":202,"TypeID":1,"Count":1,"Data":"AA=="},"Tag":700202,"IFD":700000,"Name":"JFIFYThumbnail"},{"Value":{"Palette":"","PixelData":"","Format":0},"Interoperability":{"TagID":203,"TypeID":1,"Count":0,"Data":""},"Tag":700203,"IFD":700000,"Name":"JFIFThumbnail"}]

And these are the properties read on Windows 10:

[{"Major":1,"Minor":1,"Value":257,"Interoperability":{"TagID":1,"TypeID":3,"Count":1,"Data":"AQE="},"Tag":700001,"IFD":700000,"Name":"JFIFVersion"},{"Value":1,"IsBitField":false,"Interoperability":{"TagID":101,"TypeID":1,"Count":1,"Data":"AQ=="},"Tag":700101,"IFD":700000,"Name":"JFIFUnits"},{"Value":96,"Interoperability":{"TagID":102,"TypeID":3,"Count":1,"Data":"YAA="},"Tag":700102,"IFD":700000,"Name":"XDensity"},{"Value":96,"Interoperability":{"TagID":103,"TypeID":3,"Count":1,"Data":"YAA="},"Tag":700103,"IFD":700000,"Name":"YDensity"},{"Value":0,"Interoperability":{"TagID":201,"TypeID":1,"Count":1,"Data":"AA=="},"Tag":700201,"IFD":700000,"Name":"JFIFXThumbnail"},{"Value":0,"Interoperability":{"TagID":202,"TypeID":1,"Count":1,"Data":"AA=="},"Tag":700202,"IFD":700000,"Name":"JFIFYThumbnail"},{"Value":{"Palette":"","PixelData":"","Format":0},"Interoperability":{"TagID":203,"TypeID":1,"Count":0,"Data":""},"Tag":700203,"IFD":700000,"Name":"JFIFThumbnail"},{"Value":5,"IsBitField":false,"Interoperability":{"TagID":274,"TypeID":3,"Count":1,"Data":"BQA="},"Tag":100274,"IFD":100000,"Name":"Orientation"},{"Value":{"Numerator":96,"Denominator":1,"Error":0.0},"Interoperability":{"TagID":282,"TypeID":5,"Count":1,"Data":"YAAAAAEAAAA="},"Tag":100282,"IFD":100000,"Name":"XResolution"},{"Value":{"Numerator":96,"Denominator":1,"Error":0.0},"Interoperability":{"TagID":283,"TypeID":5,"Count":1,"Data":"YAAAAAEAAAA="},"Tag":100283,"IFD":100000,"Name":"YResolution"},{"Value":2,"IsBitField":false,"Interoperability":{"TagID":296,"TypeID":3,"Count":1,"Data":"AgA="},"Tag":100296,"IFD":100000,"Name":"ResolutionUnit"},{"Value":"paint.net 4.2.16","Encoding":{"BodyName":"utf-8","EncodingName":"Unicode (UTF-8)","HeaderName":"utf-8","WebName":"utf-8","WindowsCodePage":1200,"IsBrowserDisplay":true,"IsBrowserSave":true,"IsMailNewsDisplay":true,"IsMailNewsSave":true,"IsSingleByte":false,"EncoderFallback":{"DefaultString":"�","MaxCharCount":1},"DecoderFallback":{"DefaultString":"�","MaxCharCount":1},"IsReadOnly":true,"CodePage":65001},"Interoperability":{"TagID":305,"TypeID":2,"Count":17,"Data":"cGFpbnQubmV0IDQuMi4xNgA="},"Tag":100305,"IFD":100000,"Name":"Software"}]

This is the jpeg I used for testing:

I'm playing with it on a net 6.0 project.
