How to initialize database with Entity Framework a

I have a MVC4 web application that use Entity Framework 5.0 Code First.

In Global.asax.cs I have a bootstrapper that initialize the Entity.Database, force the database to be initialized and initialize the database for the Membership. The code is this one:

System.Data.Entity.Database.SetInitializer(new DatabaseContextInitializer());
Database.Initialize(true);
WebSecurity.InitializeDatabaseConnection(DEFAULTCONNECTION, "UserProfile", "UserId", "UserName", autoCreateTables: true);

The DatabaseContextInitializer is very simple for the moment:

public class DatabaseContextInitializer : DropCreateDatabaseIfModelChanges<DatabaseContext>
{
    protected override void Seed(DatabaseContext dbContext)
    {
        base.Seed(dbContext);
        db.Set<Workout>().Add(new Workout {Id = 1, Name = "My First workout user1"})

    }
}

The problem is that I cannot create User to the membership with:

WebSecurity.InitializeDatabaseConnection(DEFAULTCONNECTION, "UserProfile", "UserId", "UserName", autoCreateTables: true);

Because I have a problem with that the database is not created. How do you initialize some default user for your database with Entity Framework 5.0 and Asp.Net MVC 4?

Take a look at the following article for the recommended approach for seeding your database using migrations.

Here are the steps:

Create a new ASP.NET MVC 4 application using the Internet Template
In your package manager console type the following command:
```
enable-migrations
```

This will create a ~/Migrations/Configuration.cs file in which you could seed your database:

using System.Data.Entity.Migrations;
using System.Linq;
using System.Web.Security;
using WebMatrix.WebData;

internal sealed class Configuration : DbMigrationsConfiguration<MvcApplication1.Models.UsersContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
    }

    protected override void Seed(MvcApplication1.Models.UsersContext context)
    {
        WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);

        if (!Roles.RoleExists("Administrator"))
        {
            Roles.CreateRole("Administrator");
        }

        if (!WebSecurity.UserExists("john"))
        {
            WebSecurity.CreateUserAndAccount("john", "secret");
        }

        if (!Roles.GetRolesForUser("john").Contains("Administrator"))
        {
            Roles.AddUsersToRoles(new[] { "john" }, new[] { "Administrator" });
        }
    }
}

Specify the memebership and role providers in your web.config:

<roleManager enabled="true" defaultProvider="SimpleRoleProvider">
  <providers>
    <clear/>
    <add name="SimpleRoleProvider" type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData"/>
  </providers>
</roleManager>
<membership defaultProvider="SimpleMembershipProvider">
  <providers>
    <clear/>
    <add name="SimpleMembershipProvider" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
  </providers>
</membership>
