FileSystemWatcher inside Docker does not notice changes to local directory

My program inside a docker container uses FileSystemWatcher to monitor a local folder. I mounted the directory with:

docker run -v /c/Users/Support/Desktop/inbox:/Users/Support/Desktop/inbox -v /c/Users/Support/Desktop/outbox:/Users/Support/Desktop/outbox -it --name workbeanRun workbean

I used Docker Exec to look into the container while it was running. It can see the inbox and outbox directories along with any files that are in it. However, when I throw a new file into the inbox, the FileSystemWatcher event does not fire. There's nothing wrong with the code because if I don't use a docker container, it runs fine.

Is there anything else I need to do in mounting the directores? Or is FileSystemWatcher even possible inside a container?

Okay, as requested, here's the program:

using System;
using System.IO;

namespace workbean
{
    class Program
    {
        FileSystemWatcher watcher = new FileSystemWatcher();
        static string sourceDir = "/Users/Support/Desktop/inbox";
        static string destDir = "/Users/Support/Desktop/outbox";


        static void Main(string[] args)
        {
            Console.WriteLine("Testing...");

            Program p = new Program();

            while (true) { }
        }


        public Program()
        {
            watcher.Path = sourceDir;
            watcher.Filter = "*.*";
            watcher.Created += new FileSystemEventHandler(OnCreated);
            watcher.EnableRaisingEvents = true;

        }


        static void OnCreated(object source, FileSystemEventArgs e)
        {

            string[] files = Directory.GetFiles(sourceDir);
            foreach (var item in files)
            {
                string destDir2 = destDir + "/" + Path.GetFileName(item);
                File.Move(item, destDir2);
            }

        }


    }
}
