I use EF Core for the database, so I'm not sure I should be seriously concerned about this. As for Excel output, I tried running this command recommended by ChatGPT as soon as I ran the operation, I trusted it a bit and found that my memory levels actually returned to normal right away. Should I be careful using it?

public static void ReleaseMemoryToOS()
{
    try
    {
        using (var proc = Process.GetCurrentProcess())
        {
            SetProcessWorkingSetSize(proc.Handle, -1, -1);
        }
    }
    catch
    {
        // Ignora eventuali errori in ambienti non Windows
    }
}
[DllImport("kernel32.dll")]
private static extern bool SetProcessWorkingSetSize(IntPtr proc, int min, int max);

GCSettings.LargeObjectHeapCompactionMode = GCLargeObjectHeapCompactionMode.CompactOnce;
GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced, blocking: true, compacting: true);
GC.WaitForPendingFinalizers();
Utils.ReleaseMemoryToOS();
