Cannot access a disposed object. Sockets C#

I use sockets, and when I try to close the socket, I get an

ObjectDisposedException: Cannot access a disposed object Object name: 'System.Net.Sockets.Socket'.

exception.

        socket.Close();
        socket.Shutdown(SocketShutdown.Both);  <- exception

Why is this happening? why does the garbage collector clean it out?

Remarks section of Socket.Close documentation tells you

For connection-oriented protocols, it is recommended that you call Shutdown before calling the Close method. This ensures that all data is sent and received on the connected socket before it is closed.

So, you should call Shutdown before Close, not the after

socket.Shutdown(SocketShutdown.Both);
socket.Close();

Close is effectively synonymous with Dispose in many cases. In the case of a socket, you should use Shutdown before Close/Dispose (or not at all).
