WebSocketManagerMiddleWare exception

When trying to use your package with latest .NET Core I am receiving this error

Message "A suitable constructor for type 'WebSocketManager.WebSocketManagerMiddleware' could not be located. Ensure the type is concrete and services are registered for all parameters of a public constructor."   string

on this line

 public static IApplicationBuilder MapWebSocketManager(this IApplicationBuilder app,
                                                              PathString path,
                                                              WebSocketHandler handler)
{
    return app.Map(path, (_app) => _app.UseMiddleware<WebSocketManagerMiddleware>(handler)); // here
}

Nevermind ... I forgot to put services.AddWebSocketManager();
