The entity type ApplicationUser is not part of the model for the current context

Question

I'm migrating from Identity 1.0.0 to Identity 2.0.1 following this article

and the migrations code generated is nothing about the new IdentityUser. It doesn't add the new columns.

So I made a new project and tried again but the migrations codes is empty.

To fix that problem, I did the edits directly in SQL Server and imported my database again in my solution.

Now my AspNetUser is exactly the same as my IdentityUser as you can see

IdentityUser

public virtual int AccessFailedCount { get; set; }

public virtual ICollection<TClaim> Claims { get; }

public virtual string Email { get; set; }

public virtual bool EmailConfirmed { get; set; }

public virtual TKey Id { get; set; }

public virtual bool LockoutEnabled { get; set; }

public virtual DateTime? LockoutEndDateUtc { get; set; }

public virtual ICollection<TLogin> Logins { get; }

public virtual string PasswordHash { get; set; }

public virtual string PhoneNumber { get; set; }

public virtual bool PhoneNumberConfirmed { get; set; }

public virtual ICollection<TRole> Roles { get; }

public virtual string SecurityStamp { get; set; }

public virtual bool TwoFactorEnabled { get; set; }

public virtual string UserName { get; set; }

IdentityUser.cs

public class ApplicationUser : IdentityUser
{
    public bool Has_accepted_policy { get; set; }
    public int user_type_id { get; set; }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {

    }
}

AspNetUser

public string Id { get; set; }

[Required]
[StringLength(256)]
public string UserName { get; set; }

public string PasswordHash { get; set; }

public string SecurityStamp { get; set; }

[StringLength(256)]
public string Email { get; set; }

public bool EmailConfirmed { get; set; }

public bool Is_Active { get; set; }

[Required]
[StringLength(128)]
public string Discriminator { get; set; }

public int? user_type_id { get; set; }

public bool Has_accepted_policy { get; set; }

public string PhoneNumber { get; set; }

public bool PhoneNumberConfirmed { get; set; }

public bool TwoFactorEnabled { get; set; }

public DateTime? LockoutEndDateUtc { get; set; }

public bool LockoutEnabled { get; set; }

public int AccessFailedCount { get; set; }

... other virtual properties 

and when I try to register a user I have the following exception

The entity type ApplicationUser is not part of the model for the current context

at this line

IdentityResult result = await UserManager.CreateAsync(user, model.Password);

My startup.Auth.cs

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

And in my AccountController I declare my UserManager like this

public AccountController()
    : this(Startup.UserManagerFactory(), Startup.OAuthOptions.AccessTokenFormat)
{
}

public AccountController(UserManager<ApplicationUser> userManager,
    ISecureDataFormat<AuthenticationTicket> accessTokenFormat)
{
    UserManager = userManager;
    AccessTokenFormat = accessTokenFormat;
}

public UserManager<ApplicationUser> UserManager { get; private set; }

I haven't changed anything except the new properties in the AspNetUser class and it used to work well before the migration.

There's a similar issue on CodePlex marked as fixed but they don't give the solution

Does anyone know how to fix this?

EDIT

To be sure I didn't do any mistakes when I edited my SQL database. I created another project and generated an Identity database and I changed the connection string for that database and I still have the same error.

SOLUTION

When I have edited my database I haven't noticed that in Identity 2.0.0 they changed the User_Id for UserId in AspUserClaims table. After doing that I had the same error but then I did what tschmit007 said about adding the ApplicationDbContext to the UserStore constructor and now it works.

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

Answer 1

I was having this same problem. I’m doing database first development with an EDMX file.
If you are using the connection string generated when adding the EDMX file in :base(“EDMXConnString”) you will most likely have this problem.

I fixed this by creating a standard connection string that pointed to the database where the ASP.NET Identity tables are.

<add name="MyConnString" connectionString="Data Source=server; Initial Catalog=db_name; User ID=user_id; Password=password; Connect Timeout=60;" providerName="System.Data.SqlClient" />

And then used that connection string in :base, and it worked!

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("MyConnString")
    {
    }
}

Answer 2

for me it seems to miss a context instanciation:

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

should be

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

Answer 3

My problem was I tried to use generated ADO.NET connection string for both generated and authentication context ApplicationDbContext. I fixed it by using a separate connection string for authentication. Also pay attention to the provider - for authentication context it has to be System.Data.SqlClient:

<add name="DefaultConnection" connectionString="Server=qadb.myserver.com;Database=mydb;User Id=myuser;Password=mypass;" providerName="System.Data.SqlClient" />

Answer 4

If you are using code first, check your connection string to ensure providerName is 'SqlClient' as in providerName="System.Data.SqlClient

If you are using database first, check your connection string to ensure providerName is 'EntityClient' as in providerName="System.Data.EntityClient
