I'm having a weird problem and I found several threads on this site that address the exact problem I'm having, but they to seem to all be able to fix their problem by setting the securitystamp in the applicationuser before running the Createasync method and making the user.
Except that doesn't solve anything for me, I keep getting an exception where it says the "value" parameter can't be null.
Here is my extended applicationuser class:
public class ApplicationUser : IdentityUser
{
[Required]
[Display(Name = "Fornavn")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public string FirstName { get; set; }
[Required]
[Display(Name = "Efternavn")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public string LastName { get; set; }
[Required]
[Display(Name = "E-mail")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public string Email { get; set; }
[Display(Name = "Profilbillede")]
public String ProfileImagePath { get; set; }
[Display(Name = "Uddannelsessted")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public String Institution { get; set; }
[Display(Name = "")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public String Semester { get; set; }
[Display(Name = "Speciale")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public String Major { get; set; }
[Display(Name = "Niveau")]
public int? Level { get; set; }
[Display(Name = "Jobtitel")]
[StringLength(50, MinimumLength = 0, ErrorMessage = "Titlen skal være på mellem 6 og 50 tegn")]
public String Position { get; set; }
[Display(Name = "Kort beskrivelse")]
[StringLength(1000, MinimumLength = 100, ErrorMessage = "Titlen skal være på mellem 100 og 1000 tegn")]
public String Description { get; set; }
public int CurrentCase { get; set; }
public int CurrentExamSet { get; set; }
}
And this is my Register method in the account controller:
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model, HttpPostedFileBase image)
{
if (ModelState.IsValid)
{
var user = model.GetUser();
if (image != null)
{
if (!Directory.Exists(Server.MapPath("~") + "/Images/ProfileImages"))
Directory.CreateDirectory(Server.MapPath("~") + "/Images/ProfileImages/");
var guid = Guid.NewGuid().ToString();
DataHelper.ResizeAndSave(Server.MapPath("~") + "/Images/ProfileImages/", guid, image.InputStream, 170);
user.ProfileImagePath = Server.MapPath("~") + "/Images/ProfileImages/" + guid + ".jpg";
}
else
{
user.ProfileImagePath = "";
}
user.SecurityStamp = Guid.NewGuid().ToString();
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
return RedirectToAction("Index", "Home");
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
It crashes on this exact line:
var result = await UserManager.CreateAsync(user, model.Password);
I've tried setting every single field value (Even in the base class) to something so that there isn't even a single field value in the applicationuser class that is null, but the error pops up anyway.
If anyone could help I would be grateful, cuz this problem is seriously annoying and I can't get further in my project.

Get user method:
public ApplicationUser GetUser()
{
var user = new ApplicationUser()
{
UserName = this.UserName,
FirstName = this.FirstName,
LastName = this.LastName,
Email = this.Email,
ProfileImagePath = ProfileImagePath,
Semester = Semester,
Major = "",
Level = 1,
Institution = Institution,
Position = "Praktikant",
Description = Description,
CurrentCase = 0,
CurrentExamSet = 0
};
return user;
}
When I step through the code, the error pops up right after it completes this method in the accountcontroler:
protected override void Dispose(bool disposing)
{
if (disposing && UserManager != null)
{
UserManager.Dispose();
UserManager = null;
}
base.Dispose(disposing);
}
Its not the SecurityStamp, its the Email property that fails on validation. IdentityUser already has an Email property so Email property of ApplicationUser "hides" the IdentityUser property.
Remove Email property from ApplicationUser to solve the probleme. Email is already required in IdentityUser. The other annotations for your localized error messages and labels put them on your RegisterViewModel.
