Based on your question and also noted in comment. 

<blockquote>
 Can someone guide me on how to update User info in the database?
</blockquote>

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

<code>IdentityResult result = await UserManager.UpdateAsync(user);</code>

<ul>
<li>Check for constrains of all field's required values </li>
<li>Check for UserManager is created using ApplicationUser.</li>
</ul>

<code>UserManager&lt;ApplicationUser&gt; UserManager = new UserManager&lt;ApplicationUser&gt;(new UserStore&lt;ApplicationUser&gt;(new ApplicationDbContext()));</code>

blocks|key|170393|text|在开发使用UpdateAsync标识的SimpleSecurity版本时，我也遇到了使用ASP.NET的问题。例如，我添加了一个功能来执行密码重置，这需要将密码重置令牌添加到用户信息中。起初，我尝试使用UpdateAsync，它得到了和你一样的结果。我最终将用户实体包装在存储库模式中，并使其正常工作。您可以查看SimpleSecurity+project+for+an+example。在使用ASP.NET+Identity+more之后(文档仍然不存在)，我认为UpdateAsync只是将更新提交到上下文，您仍然需要保存上下文以便提交到数据库。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|170394|entityMap|0|LINK|mutability|MUTABLE|url|https://simplesecurity.codeplex.com/|1|https://simplesecurity.codeplex.com/SourceControl/latest#AspNetIdentity/SimpleSecurity.AspNetIdentity/WebSecurity.cs^0|J|E|0|4C|11|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

I also had problems using UpdateAsync when developing a version of <a href="https://simplesecurity.codeplex.com/" rel="nofollow">SimpleSecurity</a> 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 <a href="https://simplesecurity.codeplex.com/SourceControl/latest#AspNetIdentity/SimpleSecurity.AspNetIdentity/WebSecurity.cs" rel="nofollow">SimpleSecurity project for an example</a>. 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 <code>UserManager.Updateasync</code> method it succeeds but there is no update in the database. After spending some time i found another solution to update the data in <code>aspnetusers</code> table which is following:

1) you need to create <code>UserDbContext</code> class inheriting from <code>IdentityDbContext</code> class like this:

<pre><code>public class UserDbContext:IdentityDbContext&lt;UserInfo&gt;
{
 public UserDbContext():
 base("DefaultConnection")
 {
 this.Configuration.ProxyCreationEnabled = false;
 }
}
</code></pre>

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

<pre><code>UserDbContext userDbContext = new UserDbContext();
userDbContext.Entry(user).State = System.Data.Entity.EntityState.Modified;
await userDbContext.SaveChangesAsync();
</code></pre>

where <code>user</code> is your updated entity.

hope this will help you.

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

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

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

<pre><code>class AspNetUser :IdentityUser
</code></pre>

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

<pre><code>public partial class MyContext : IdentityDbContext&lt;AspNetUser&gt;
</code></pre>

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

<pre><code> public static void UpdateAspNetUser(AspNetUser user, string[] props)
 {
 MyContext context = new MyContext();
 UserStore&lt;AspNetUser&gt; store = new UserStore&lt;AspNetUser&gt;(context);
 Task&lt;AspNetUser&gt; 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();
 }
</code></pre>

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

<pre><code> UserManagerFactory = () =&gt; new UserManager&lt;ApplicationUser&gt;(new UserStore&lt;ApplicationUser&gt;(new ApplicationDbContext()));

 OAuthOptions = new OAuthAuthorizationServerOptions

 Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
 AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
 AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
 AllowInsecureHttp = true
 };
</code></pre>

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.

If you leave any of the fields for ApplicationUser OR IdentityUser null the update will come back as successful but wont save the data in the database. 

Example solution:

<pre><code>ApplicationUser model = UserManager.FindById(User.Identity.GetUserId())
</code></pre>

Add the newly updated fields:

<pre><code>model.Email = AppUserViewModel.Email;
model.FName = AppUserViewModel.FName;
model.LName = AppUserViewModel.LName;
model.DOB = AppUserViewModel.DOB;
model.Gender = AppUserViewModel.Gender;
</code></pre>

Call UpdateAsync

<pre><code>IdentityResult result = await UserManager.UpdateAsync(model);
</code></pre>

I have tested this and it works.

OK... I spent hours trying to figure why <code>userManager.updateAsync</code> would not persist the user data that we edit ... until I reached the following conclusion:

The confusion arises from the fact that we create the <code>UserManager</code> in one line like this:

<pre><code>var manager = new UserManager&lt;ApplicationUser&gt;(new UserStore&lt;ApplicationUser&gt;(new MyDbContext()));
</code></pre>

...then we use <code>manager.UpdateAsync( user );</code> but that will update the user in the context, and then we will need to save changes to the dbcontext of the Identity. So, the question is how to get the Identity DBcontext in the easiest way.

To solve this, we should not create the <code>UserManager</code> in one line ... and here is how I do it:

<pre><code>var store = new UserStore&lt;ApplicationUser&gt;(new MyDbContext());
var manager = new UserManager(store);
</code></pre>

then after updating the user by calling 

<pre><code>manager.UpdateAsync(user);
</code></pre>

then you go to the context

<pre><code>var ctx = store.context;
</code></pre>

then

<pre><code>ctx.saveChanges();
</code></pre>

wahooooooo...persisted :)

I am using the new EF &amp; Identity Core and I have the same issue, with the addition that I've got this error: 

<blockquote>
 The instance of entity type cannot be tracked because another instance

</blockquote>

With the new DI model I added the constructor's Controller the context to the DB.

I tried to see what are the conflict with <code>_conext.ChangeTracker.Entries()</code> and adding <code>AsNoTracking()</code> to my calls without success.

I only need to change the state of my object (in this case Identity) 

<pre><code>_context.Entry(user).State = EntityState.Modified;
var result = await _userManager.UpdateAsync(user);
</code></pre>

And worked without create another store or object and mapping.

I hope someone else is useful my two cents.

I am using .Net Core 3.1 or higher version.Please follow the solution:
<pre><code> public class UpdateAssignUserRole
 {
 public string username { get; set; }
 public string rolename { get; set; }
 public bool IsEdit { get; set; }

 }

 private async Task UpdateSeedUsers(UserManager&lt;IdentityUser&gt; userManager, UpdateAssignUserRole updateassignUsername)
 {
 IList&lt;Users&gt; Users = await FindByUserName(updateassignUsername.username);

 if (await userManager.FindByNameAsync(updateassignUsername.username) != null)
 {
 var user = new IdentityUser
 {
 UserName = updateassignUsername.username,
 Email = Users[0].Email,
 
 };
 var result = await userManager.FindByNameAsync(updateassignUsername.username);
 if (result != null)
 {
 IdentityResult deletionResult = await userManager.RemoveFromRolesAsync(result, await userManager.GetRolesAsync(result));
 if (deletionResult != null)
 {
 await userManager.AddToRoleAsync(result, updateassignUsername.rolename);
 }
 }
 }

 }
</code></pre>

I've added custom fields to the <code>ApplicationUser</code> class 
I've also created a form through which the user can enter/edit the fields. 
However for some reason I'm not able to update the fields in the database.

<pre><code>[HttpPost]
[ActionName("Edit")]
[ValidateAntiForgeryToken]
public async Task&lt;ActionResult&gt; Manage(EditProfileViewModel model)
{
 if (ModelState.IsValid)
 {
 // Get the current application user
 var user = User.Identity.GetApplicationUser();

 // Update the details
 user.Name = new Name { First = model.FirstName, Last = model.LastName, Nickname = model.NickName };
 user.Birthday = model.Birthdate;

 // This is the part that doesn't work
 var result = await UserManager.UpdateAsync(user);

 // However, it always succeeds inspite of not updating the database
 if (!result.Succeeded)
 {
 AddErrors(result);
 }
 }

 return RedirectToAction("Manage");
}
</code></pre>

My problem is similar to <a href="https://stackoverflow.com/questions/19348966/mvc5-applicationuser-custom-properties">MVC5 ApplicationUser custom properties</a>, but that seems to use an older version of Identity because the IdentityManager class doesn't seem to exist.

Can someone guide me on how to update <code>User</code> info in the database?

UPDATE:
If I include all the fields in the register form, all the values are stored in the appropriate field in a new record of the <code>Users</code> table from the database.

I don't know to make changes to the fields of an existing user (row in the <code>users</code> table). <code>UserManager.UpdateAsync(user)</code> doesn't work.

Also note my issue is more Identity oriented than EntityFramework

我已经向ApplicationUser类添加了定制字段我还创建了一个表单，用户可以通过它输入/编辑字段。但是，由于某些原因，我无法更新数据库中的字段。[HttpPost][ActionName("Edit")][ValidateAntiForgeryToken]public async Task<ActionResul...
