TCP async socket file transfer server and client c#

It is necessary to develop an asynchronous TCP socket server to which several clients will be connected at the same time and to which each file will be transferred for each client and on the client side the file should be received and written to a folder on a disk. Work logic: 1. The client connects via a socket to the server and transmits its ID 2. The server connects to the client, reads its ID and sends the file to it according to the ID (Directory "ID" .xlsx) 3. The client receives the file Reference "ID" .xlsx, writes it to a folder and terminates the connection with the server 4. The server enters standby mode for a new client connection. The server must be able to receive multiple clients at once and send them the files of the day at the same time
