Extension unload problem

Code:

public class ZeroLoader : PluginLoader
    {
        private Dictionary<string, Type> plugins = new Dictionary<string, Type>();        public ZeroLoader()
        {
            this.GetType().Assembly.GetTypes().Where(t => t.Namespace == "Oxide.Ext.Zero.Plugins").ToList().ForEach(t => plugins.Add(t.Name, t));
        }        public override Plugin Load(string directory, string name)
        {
            if (plugins.ContainsKey(name))
            {
                object obj = Activator.CreateInstance(plugins[name], true);
                if (obj != null)
                {
                    Plugin plugin = (Plugin) obj;
                    return plugin;
                } else
                    Interface.Oxide.LogError("Plugin <"+name+"> is not initialized!");
            }
            return null;
        }        public override IEnumerable<string> ScanDirectory(string directory) => plugins.Keys;
    }

Code:

public class ZeroExtension : Extension
    {
        public ZeroExtension(ExtensionManager manager) : base(manager) { }        public override string Name => "Zero";
        public override string Author => "TheRyuzaki";
        public override VersionNumber Version => new VersionNumber(0,0,1);        public override void Load()
        {
            SingletonType<ZeroExtension>.Setup(this);
            Manager.RegisterPluginLoader(SingletonType<ZeroLoader>.Instance);
        }
    }

Code:

 public class ZeroPlayer : RustPlugin
    {
        public ZeroPlayer()
        {
            this.Name = this.GetType().Name;
            this.Author = SingletonType<ZeroExtension>.Instance.Author;
            this.Version = new VersionNumber(0,0,1);
        }        private void Unload() => Interface.Oxide.LogWarning("Unload");
        private void Loaded() => Interface.Oxide.LogWarning("Loaded");    }

What is it? Need fixed =(

 

Code:

public override Plugin Load(string directory, string name)
        {
            if (plugins.ContainsKey(name))
            {
                object obj = Activator.CreateInstance(plugins[name], true);
                if (obj != null)
                {
                    CSharpPlugin plugin = (CSharpPlugin) obj;
                    plugin.Loader = this;
                    plugin.Watcher = new FSWatcher(Interface.Oxide.PluginDirectory, ".zero");
                    return plugin;
                } else
                    Interface.Oxide.LogError("Plugin <"+name+"> is not initialized!");
            }
            return null;
        }

this is good code - Oxide default - dont have Watcher to plugin!
