ZipFile Class not recognised by visual studio

I am trying to use ZipFile.OpenRead() but the thing is no matter how much i try it is not working in the program, whatever nugetpackage or code i use.

I tried System.IO.Compression.ZipFile.OpenRead() this did not work, instead I was asked to use ZipArchive by visual studio.

I imported both System.IO.Compression.ZipFile and System.IO.Compression nuget packages but still there is no change, what more can i do?

The code is here: Link, Line no. 167.
