The solution for this problem is to comment in ProjectName\Areas\HelpPage\Controllers\HelpController.cs the constructors like this:

    public class HelpController : Controller
        {
            private const string ErrorViewName = "Error";

    //        public HelpController()
    //            : this(GlobalConfiguration.Configuration)
    //        {
    //        }

    //        public HelpController(HttpConfiguration config)
    //        {
    //            Configuration = config;
    //        }

            /// 

            /// GlobalConfiguration By default
            /// 
            protected static HttpConfiguration Configuration
            {
                get { return GlobalConfiguration.Configuration; }
            }

            public ActionResult Index()
            {
                ViewBag.DocumentationProvider = Configuration.Services.GetDocumentationProvider();
                return View(Configuration.Services.GetApiExplorer().ApiDescriptions);
            }
....

The default constructor is not called;

The second method is to inject the default constructor by add this attribute [InjectionConstructor] on default constructor like this:

public class HelpController : Controller
    {
        private const string ErrorViewName = "Error";

         [InjectionConstructor]
        public HelpController()
            : this(GlobalConfiguration.Configuration)
        {
        }

        public HelpController(HttpConfiguration config)
        {
            Configuration = config;
        }

        /// 

        /// GlobalConfiguration By default
        /// 
        protected static HttpConfiguration Configuration { get; private set; }
....
