Why TcpListener does not implement IDisposable

Question

To better understand how the .NET networking part works, I'm going through the reference source of the TcpListener( Documentation , Reference Source ) class. What caught my attention is that it owns the object implementing IDisposable (Socket) but does not implement IDisposable itself. Is there a reason for this?

Answer 1

Because when you use the IPEndPoint based constructor , the TcpListener doesn't own the socket. It would be very rude to dispose of said socket if you planned on reusing said IPEndPoint object
