I have been working on the Forgotten Password using razor. here is my code 

1. [HttpPost]
2.         [Authorize]
3. [ValidateAntiForgeryToken]
4.         public ActionResult HandleForgottenPassword(ForgottenPasswordViewModel model)
5.         {
6.             if (!ModelState.IsValid)
7.             {
8.                 return PartialView("ForgottenPassword", model);
9.             }
11.             //Find the member with the email address
12.             var findMembername = Member.GetMemberFromEmail(model.LoginName);
13.             var findMember = Member.GetMemberFromEmail(model.EmailAddress);
15.             if (findMember != null)
16.             {
17.                 //We found the member with that email
19.                 //Set expiry date to 
20.                 DateTime expiryTime = DateTime.Now.AddMinutes(15);
22.                 //Lets update resetGUID property
23.                 findMember.getProperty("resetGUID").Value = expiryTime.ToString("ddMMyyyyHHmmssFFFF");
25.                 //Save the member with the up[dated property value
26.                 findMember.Save();
28.                 //Send user an email to reset password with GUID in it
29.                 EmailHelper email = new EmailHelper();
30.                 email.SendResetPasswordEmail(findMember.Email, expiryTime.ToString("ddMMyyyyHHmmssFFFF"));
31.             }
32.             else
33.             {
34.                 ModelState.AddModelError("ForgottenPasswordForm.", "No member found");
35.                 return PartialView("ForgottenPassword", model);
36.             }
38.             return PartialView("ForgottenPassword", model);
39.         }
