@Randor

Thanks to David (aka Randor) !

Well, turns out I did not look deeply enough into the EmsiSoft AV/Firewall records, as David suggested.

Note: size of test file saved as .xml 1017; size saved as .gz 369.

EmsiSoft was quarantining the WinForm app .exe. I set permission for the entire folder containing my C# work in progress ...code works ... ... setting permission for VS 2019 and 2022 had no effect. Why the whole folder ? I was too lazy to set it for one specific project.

Here's what the kinks were:

1. no run-time notification pop-up from EmsiSoft which is normally ... a frequent popper-upper. And, once quarantined, why should the app run partially at all ? I will write about this to them, and, aaso ask them what could happen if I were using GitHub storage.

2. why should standard XML writing:
using (var writer = new FileStream(fullfilename, FileMode.OpenOrCreate, FileAccess.Write
                   //FileIOPermissionAccess.AllAccess
               ))
        {
            dcs.WriteObject(writer, instance);
        }
work, but, why does this:
using (FileStream compressedFileStream = new FileStream(fullfilename, FileMode.OpenOrCreate, FileAccess.Write))
{
    using (GZipStream compressionStream =
           new GZipStream(compressedFileStream, CompressionLevel.Optimal, false))
    {
        dcs.WriteObject(compressionStream, instance);
        compressionStream.Close();
    }
}
trigger AV interception ? Is there an MS bug here ?
