Updating user data - ASP.NET Identity

I also had problems using UpdateAsync when developing a version of SimpleSecurity that uses ASP.NET Identity. For example, I added a feature to do a password reset that needed to add a password reset token to the user information. At first I tried using UpdateAsync and it got the same results as you did. I ended up wrapping the user entity in a repository pattern and got it to work. You can look at the SimpleSecurity project for an example. After working with ASP.NET Identity more (documentation is still non-existent) I think that UpdateAsync just commits the update to the context, you still need to save the context for it to commit to the database.

I have tried the functionality in the same way and when i call UserManager.Updateasync method it succeeds but there is no update in the database. After spending some time i found another solution to update the data in aspnetusers table which is following:

1) you need to create UserDbContext class inheriting from IdentityDbContext class like this:

public class UserDbContext:IdentityDbContext<UserInfo>
{
    public UserDbContext():
        base("DefaultConnection")
    {
        this.Configuration.ProxyCreationEnabled = false;
    }
}

2) then in Account controller update user information like this:

UserDbContext userDbContext = new UserDbContext();
userDbContext.Entry(user).State = System.Data.Entity.EntityState.Modified;
await userDbContext.SaveChangesAsync();

where user is your updated entity.

hope this will help you.

The UserManager did not work, and As @Kevin Junghans wrote,

UpdateAsync just commits the update to the context, you still need to save the context for it to commit to the database

Here is quick solution (prior to new features in asp.net identity v2) I used in a web forms project. The

class AspNetUser :IdentityUser

was migrated from SqlServerMembership aspnet_Users. And the context is defined:

public partial class MyContext : IdentityDbContext<AspNetUser>

I apologize for the reflection and synchronous code--if you put this in an async method, use await for the async calls and remove the Tasks and Wait()s. The arg, props, contains the names of properties to update.

 public static void UpdateAspNetUser(AspNetUser user, string[] props)
 {
     MyContext context = new MyContext();
     UserStore<AspNetUser> store = new UserStore<AspNetUser>(context);
     Task<AspNetUser> cUser = store.FindByIdAsync(user.Id); 
     cUser.Wait();
     AspNetUser oldUser = cUser.Result;

    foreach (var prop in props)
    {
        PropertyInfo pi = typeof(AspNetUser).GetProperty(prop);
        var val = pi.GetValue(user);
        pi.SetValue(oldUser, val);
    }

    Task task = store.UpdateAsync(oldUser);
    task.Wait();

    context.SaveChanges();
 }

As always, thanks in advance for constructive criticism.

If you don't have every single field for ApplicationUser as well as IdentityUser the update will come back as successful but wont save the data in the database. If you have every last piece of data then it will save properly.

My solution is pretty simple:

ApplicationUser Model = UserManager.FindById(User.Identity.GetUserId())

Than simply add the newly updated fields:

Model.Email = AppUserViewModel.Email;
Model.FName = AppUserViewModel.FName;
Model.LName = AppUserViewModel.LName;
Model.DOB = AppUserViewModel.DOB;
Model.Gender = AppUserViewModel.Gender;

Than call the async

IdentityResult result = await UserManager.UpdateAsync(Model);

I have thoroughly tested this and it works perfectly.

Add the following code to your Startup.Auth.cs file under the static constructor:

        UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

        OAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
            AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            AllowInsecureHttp = true
        };

The UserManagerFactory setting line of code is what you use to associate your custom DataContext with the UserManager. Once you have done that, then you can get an instance of the UserManager in your ApiController and the UserManager.UpdateAsync(user) method will work because it is using your DataContext to save the extra properties you've added to your custom application user.

Based on your question and also noted in comment.

Can someone guide me on how to update User info in the database?

Yes, the code is correct for updating any ApplicationUser to the database.

IdentityResult result = await UserManager.UpdateAsync(user);

• Check for constrains of all field's required values
• Check for UserManager is created using ApplicationUser.

UserManager<ApplicationUser> UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
