MVC 5 - RedirectToAction Not Redirecting

Question

Hi I have a problem with my RedirectToAction not redirecting. My code successfully hits a breakpoint placed on the Redirect so I can confirm it is being called. Nothing seems to happen however.

I have tried looking at the network traffic in Chrome and there doesn't seem to be anything obvious. I must be missing something simple!

    //
    // POST: /Blog/CreateBlog
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult CreateBlog(BlogViewModel model)
    {
        var userId = User.Identity.GetUserId();
        model.UserId = userId;

        if (ModelState.IsValid && model.UserId != null)
        {
            Mapper.CreateMap<BlogViewModel, Blog>();
            if (_blogProcess.CreateBlog(Mapper.Map<BlogViewModel, Blog>(model)))
            {
                RedirectToAction("Index", "Blog");
            }
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

Answer 1

try

return RedirectToAction("Index", "Blog");

Answer 2

In addtion to Nalaka526's answer: if we look into the documentation for RedirectToAction we can see that it's an instance method of the Controller class which has RedirectToRouteResult as return type, which derives from ActionResult which indicates that we have to return it, just like we return View and PartialView for example.
