Enable migrations with reference to ApplicationUser identity framework code first

Question

I'll create a database with identity framework (code first way) but I've errors when I run code below in the package manager.

PM> Enable-Migrations -ContextTypeName FreeTime.AspMvc.Context.FreeTimeContext -Force

Here are my errors:

• IdentityUserLogin: : EntityType IdentityUserLogin has no key defined. Define the key for this EntityType.

• IdentityUserRole: : EntityType IdentityUserRole has no key defined. Define the key for this EntityType.

• IdentityUserLogins: EntityType: EntitySet IdentityUserLogins is based on type IdentityUserLogin that has no keys defined.

• IdentityUserRoles: EntityType: EntitySet IdentityUserRoles is based on type IdentityUserRole that has no keys defined.

In other classes I've made a property type of ApplicationUser named UserId and one of type of string named User for holding witch user has made witch topic. Here you've an example:

public class Topic 
{
    [Key]
    public int TopicId { get; set; }

    [ForeignKey("dbo.AspNetUsers.Id")]
    public string UserId { get; set; }

    public ApplicationUser User { get; set; }
}

Small update: Here is my context file:

public class FreeTimeContext: DbContext
{
    public DbSet<Topic> Topics { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
    }
}

I've also seen that there is a second context file named ApplicationDbContext.

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("FreeTimeContext" /* --> this I've edited into my own name */,
               throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

Big update: In a later state I've tried other things like list below:

1. First I've tried to enabled the migrations for ApplicationDbContext. Here are the steps I've done.

   • First I've run this code:

     PM> enable-migrations -ContextTypeName FreeTime.AspMvc.Models.ApplicationDbContext -Force

     This is done without errors.

   • Then I've run this:

     PM> add-migration "initAspTables"

     Also no problems with this code.

   • Finaly I've update my database:

     PM> Update-Database

     Also done with no problems.

   • Check if the tables are created into the server manager → Check but doesn't contain my own tables. ☹

     

   Conclusion: not really what I will have.

2. Second thing I've done is inherit FreeTimeContext from ApplicationContext instead of DbContext like code below.

   public class FreeTimeContext: ApplicationDbContext
   {
       public DbSet Topics { get; set; }
   
       public FreeTimeContext(): base() 
       { }
       // other code
   }

   And again to try enable the migrations with this code:

   PM> enable-migrations -ContextTypeName FreeTime.AspMvc.Context.FreeTimeContext -Force

   but I've this error:

   The ForeignKeyAttribute on property UserId on type FreeTime.AspMvc.Models.Topic is not valid. The navigation property dbo.AspNetUsers.Id was not found on the dependent type FreeTime.AspMvc.Models.Topic. The Name value should be a valid navigation property name.

   Conclusion: didn't work.

Can you help me? I don't know what else I could do to migrate the class ApplicationUser together with my own classes to the database.
