I am trying to reconnect to a socket that I have disconnected from but it won't allow it for some reason even though I called the Disconnect method with the argument "reuseSocket" set to true.

_socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
_socket.Connect(ipAddress, port);
//...receive data
_socket.Disconnect(true); //reuseSocket = true
//...wait
_socket.Connect(ipAddress, port); //throws an InvalidOperationException:

Once the socket has been disconnected, you can only reconnect again asynchronously, and only to a different EndPoint. BeginConnect must be called on a thread that won't exit until the operation has been completed.

What am I doing wrong?
