MVC 5 Not Auto Creating AspNetUser tables in DB

Question

I am new to MVC 5 and I am trying to configure Individual User Auth in a new database context created but the ApplicationDBContext isn't creating the AspNetUser tables in my new database. Can someone point me in the right direction on this?

Error

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

IdentityModel.cs

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("MyEntities", throwIfV1Schema: false)
    {
    }

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

Web.config

<connectionStrings>
  <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-MVC5.WebSite-20150723075149.mdf;Initial Catalog=aspnet-MVC5.WebSite-20150723075149;Integrated Security=True" providerName="System.Data.SqlClient" />
  <add name="MyEntities" connectionString="metadata=res://*/Models.UserModel.csdl|res://*/Models.UserModel.ssdl|res://*/Models.UserModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=devserver;initial catalog=MyEntities;user id=user;password=pass;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

I know MVC is supposed to auto-magically create the UserStore and associated tables but clearly I've done something totally stupid here. Any help is much appreciated.

Answer 1

Are you using code first migrations?

normally, you have to enable migrations, create new migrations and apply them in order to create your db.

Go in package manager console and execute the following commands

enable-migrations
add-migration initial
update-database

EDIT

if you don't want to use migrations, you can also put this in the constructor of your context:

Database.SetInitializer<ApplicationDbContext>(new DropCreateDatabaseIfModelChanges<ApplicationDbContext>());

but you will lose your data everytime the db is re-created

Answer 2

Okay, I was doing something stupid. Basically trying to get the ApplicationDbContext to use a connection that was created by EF. Not the right way. To get the tables 'auto-magically` created. I needed to add a normal connection string to my Web.config connecting to the desired DB then set that in the IdentityModel.cs

Web.config

<connectionStrings>
  <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-MVC.WebSite-20150723075149.mdf;Initial Catalog=aspnet-MVC.WebSite-20150723075149;Integrated Security=True" providerName="System.Data.SqlClient" />
  <add name="MyConnection" connectionString="Data Source=devserver;initial catalog=MyCatalog;user id=user;password=pass;Integrated Security=True" providerName="System.Data.SqlClient" />
 </connectionStrings>

IdentityModel.cs

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("MyConnection", throwIfV1Schema: false)
    {
    }

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

Hopefully, this helps someone. Thanks to all who helped.

If you need to recreate the tables, here's the generation scripts for ASP.net EF 2.2

 <add name="DefaultConnection" connectionString="Server=yourservername;Database=yourdbname;User Id=yourusername;Password=yourpassword;" providerName="System.Data.SqlClient" />

just make this connection string in web.config then run the application,than register a account. check now your database.
