Hi,

I'm trying to get SimpleInjector to work with a SurfaceController but get the following error:

Exception message: No parameterless constructor defined for this object.

I currently using

• Umbraco 7.2.3
• SimpleInjector.Integration.Web.Mvc 3.0.5
• In an external project I have Entity Framework 6

This is my setup

  public class Startup : Umbraco.Web.UmbracoApplication
{
    protected override void OnApplicationStarted(object sender, EventArgs e)
    {
        base.OnApplicationStarted(sender, e);

        // Create the container as usual.
        var container = new Container();
        container.Options.DefaultScopedLifestyle = new WebRequestLifestyle();

        // Register your types, for instance:
        //Does not help issue: container.Register(()=> UmbracoContext.Current, Lifestyle.Singleton);
        container.Register<IDataContext, PortalDataContext>(Lifestyle.Singleton);

        // This is an extension method from the integration package.
        container.RegisterMvcControllers(Assembly.GetExecutingAssembly());

        // This is an extension method from the integration package as well.
        container.RegisterMvcIntegratedFilterProvider();

        container.Verify();

        DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));
    }
}

And here's my class trying to use it

 public class RegisterFormSurfaceController : SurfaceController
{

    public RegisterFormSurfaceController(IDataContext dataContext)
    {
        _dataContext = dataContext;
    }

    private IDataContext _dataContext { get; }

    public ActionResult GetRegister()
    {
        var model = new RegisterFormViewModel();
        var optionsMobile =
            (from c in _dataContext.Countries
                select new OptionModel
                {
                    Id = c.CountryID,
                    Value = $"{c.CountryName} ({c.DialCode})"
                }).ToList();

        model.MobileNumberPrefixOptions = optionsMobile;

        return PartialView("~/Views/Partials/RegisterForm.cshtml", model);
    }

I've tried various options with no joy, any help is appreciated.

Kind regards and many thanks
