    public HomeController(Areas.Api.Controllers.FoobarController foobarController)
    {

    }

    private void InitControllers()
    {
        // We can't set this at Ctor because we don't have our local copy yet
        // Access to Url 
        _foobarController.Url = Url;
        // Access to User
        _foobarController.ActionContext = ActionContext;
        // For more references see https://github.com/aspnet/Mvc/blob/6.0.0-rc1/src/Microsoft.AspNet.Mvc.ViewFeatures/Controller.cs

        var model = new IndexViewModel();
        model.Foo = _foobarController.List(new FoobarRequest() { Foo = true, Bar = false });
        model.Bar = _foobarController.List(new FoobarRequest() { Foo = false, Bar = true });
