Add a reference & 'using' statement for System.IO.Compression.FileSystem

ref : ZipArchive Constructor (System.IO.Compression) | Microsoft Docs[^] - using the 'stream constructor' gets-around having to add an entire directory

using (FileStream fs = new FileStream(@"drive:\path\file.zip",FileMode.Create))
using (ZipArchive zArchive = new ZipArchive(fs, ZipArchiveMode.Create))
{
    zArchive.CreateEntryFromFile(@"drive:\path\xml-file.xml", "xml-file.xml");
}
