NetworkManager.Shutdown

Description

Shuts down the NetworkManager completely and destroy the singleton.

This is required if a new NetworkManager instance needs to be created after the original one was destroyed. The example below has a reference to the GameObject with the NetworkManager on it and destroys the instance before calling Shutdown() and switching scenes.

using UnityEngine;
using UnityEngine.Networking;

public class SwitchToEmptyScene : MonoBehaviour
{
    public GameObject NetworkManagerGameObject;

    void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 200, 20), "Switch"))
        {
            Destroy(NetworkManagerGameObject);
            NetworkManager.Shutdown();

            Application.LoadLevel("empty");
        }
    }
}

This cleanup allows a new scene with a new NetworkManager to be loaded.
