return view stopped working - asp.net-mvc

Question

I've modified the mvc5 registration to allow the user to upload a profile image. Everything works fine, the file gets uploaded, the database get properly populated, and the email confirmation email gets sent.
The problem is that since adding the file handling code, the return view("info") no longer does anything, the registration page just refreshes instead. I've stepped through the code, and it's still hitting return view("info") without any problems. Anybody know the cause/solution? I was wondering if it was something to do with the register action being a async?
Here's the code:
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var userD = new UserDetails();
userD.Name = model.Name;
Regex rgx = new Regex("[^a-zA-Z0-9]");
string UserFolder = rgx.Replace(model.Email + DateTime.Now, "");
userD.UserRootFolder = UserFolder;
//create root folder
string RootPath = #"~/UserFiles/" + UserFolder + "/";
//check it doesnt already exist
if (!Directory.Exists(Server.MapPath(RootPath)))
{
//create the directory
DirectoryInfo di = Directory.CreateDirectory(Server.MapPath(RootPath));
if(!di.Exists)
{
//if the folder still doesnt exist return to view as something went wrong
//return View(model);
}
userD.UserRootFolder = RootPath;
}
HttpPostedFileBase TheFile = model.file;
if (TheFile != null)
{
string path = Server.MapPath(RootPath + model.file.FileName);
model.file.SaveAs(path);
userD.UserPictureLocation = path;
model.file.InputStream.Close();
}
var user = new ApplicationUser
{
UserName = model.Email,
Email = model.Email,
PaypalEmail=model.PaypalEmail,
UserDetails = userD
};
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
code = System.Web.HttpUtility.UrlEncode(code);
var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking here");
ViewBag.Message = "Check your email and confirm your account, you must be confirmed "
+ "before you can log in.";
return View("info");
// return RedirectToAction("Index", "Home");
}
AddErrors(result);
}
// If we got this far, something failed, redisplay form
return View(model);
}

Answer 1

Do you know if debugging and waiting the email be sent you can render your screen?
A: If it's Yes, I think it's better you register this CONFIRMATION EMAIL in the DB and them make another call to send ALL CONFIRMATION EMAIL that hasn't been sent.
By the way, could you share the code of your View Info and the path?

Answer 2

I've fixed it. I've no idea why, but saving the image after the email gets sent got it working again.
If anyone knows why, then i'd love to know.
