Read image metadata(GPS data) from android and IOS

Question

I am trying to read metadata (GPS data) of the images captured from android and IOS devices in C#. I can read metadata of images captured from android device using open source library. But I could not read metadata of images captured from IOS device,  could not find GPS data for images captured from IOS device. I am looking for common open source library that can read metadata of images captured from both android and IOS devices. Please suggest me any open source library or any working solution for this problem. I would like to thank for your help in advance.
