1. You can get all emails, not only those with unseen flag: just use Imap.GetAll() method.

2. You can mark message as unseeen using Gmail online interface: just mark the mail, click "more actions", and click "mark as unread"

3. You can save last processed uid in your windows application:

Here's the code:

long lastProcessedUID = GetLastProcessedUID(); // returns -1 on first run
using (Imap client = new Imap())
{
   List<long> allUids = client.GetAll();
   List<long> toBeProcessed = allUids.FindAll(x => x > lastProcessedUID);

   foreach (long uid in toBeProcessed)
   {
       // process message here

       SaveLastProcessed(uid);
   }
   client.Close();
}
