How to get the list of newly created files during an application instance in a certain directory?

Question

I would like to know how I can get the list of newly created files during an application instance in a certain directory when my application was open.

Just to be clear: Every time my application is opened, few files get generated in a certain directory, I want the list of only those files which got created after the application was opened.

Use FileWatcher

    FileSystemWatcher watcher = new FileSystemWatcher();
    watcher.Path = @"C:\temp";
    watcher.NotifyFilter =  NotifyFilters.FileName;
    watcher.Filter = "*.*";
    watcher.Created += new FileSystemEventHandler(OnCreated);
    watcher.EnableRaisingEvents = true;

    private static void OnCreated(object sender, FileSystemEventArgs e)
    {
        Console.WriteLine($"File created {e.Name}");
    }
