Identity 2.1 - UserId not found but was working before

Question

This code worked before numerous times but after adding in a couple new properties for a user in Identity 2.1 it has ceased to work suddenly. I am getting a UserId not found error, despite there being a value visible in the debugger for UserId. Anyone have an idea on why this has suddenly happened? It's very frustrating to see the least.

Here's code: (Controller)

 // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        model.BackgroundOnFile = false;

        if (ModelState.IsValid)
        {
            var userDetails = new ApplicationUser { UserName = model.Email, Title = model.Title, Email = model.Email, FirstName = model.FirstName, LastName = model.LastName, LEAID = model.LEAID, SchoolID = model.SchoolID, Address1 = model.Address1, Address2 = model.Address2, City = model.City, State = model.State, PostCode = model.PostCode, BackgroundOnFile = model.BackgroundOnFile, BoardStart = model.BoardStart, BoardEnd = model.BoardEnd, PhoneNumber = model.PhoneNumber };
            var result = await UserManager.CreateAsync(userDetails, model.Password);


            //Assign Role
            UserManager.AddToRole(userDetails.Id, "User");

            if (result.Succeeded)
            {
                await SignInManager.SignInAsync(userDetails, isPersistent:false, rememberBrowser:false);

                // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
                // Send an email with this link
                // string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
                // 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 <a href=\"" + callbackUrl + "\">here</a>");

                return RedirectToAction("Index", "Home");
            }
            AddErrors(result);
        }

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

And the Model:

public class ApplicationUser : IdentityUser
{

    //Extra items required to register
    public string Title { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int LEAID { get; set; }
    public int SchoolID { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    //Post Code is a string to accomodate future possible Canadian style post codes
    public string PostCode { get; set; }
    public bool BackgroundOnFile { get; set; }
    public System.DateTime BoardStart { get; set; }
    public System.DateTime BoardEnd { get; set; }
    public string NominatedBy { get; set; }


    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }
}

And the error:

UserId not found.

Answer 1

This exception is not generated by Application User class, there is no property named UserID in this class. (its Id not UserId)

So there are two Tables in Identity database contains column with UserID

1. IdentityRole
2. IdentityUserRole

Therefore exception is being raised during insert in these tables, there is nothing wrong with ApplicationUser.Id. Make sure that role with name "User" exists. also check for name case i.e. "User"/"user"

Answer 2

If, like me, you struggle to get identity framework working without fully appreciating all the ins and outs, this may help. I was using this line to get a reference to the user:

var user = new ApplicationUser { UserName = ...

This creates a new user. What I should have done is use this line:

var user = UserManager.FindByEmail( ...

You can then reset the password like this:

string code = UserManager.GeneratePasswordResetToken(user.Id);
var result = UserManager.ResetPassword(user.Id, code, model.Password);

Note that this has no error-checking.

Answer 3

Having the same error right now! The only relevant recent action I've made is the update of packages through NuGet:

• EntityFramework 6.1.1 to 6.1.3
• Microsoft ASP.NET IdentityCore 2.1.0to 2.2.1
• Microsoft ASP.NET Identity EntityFramework 2.1.0 to 2.2.1
• Microsoft ASP.NET Identity Owin 2.1.0 to 2.2.1

Still investigating anyway...

UPDATE

In my case I was trying to generate the confirmation token before saving the user. I learned that UserManager.GenerateEmailConfirmationTokenAsync(userID) generates the token upon a saved ID, not the one you have in memory.

Hope this helps, somehow.
