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

Here are the steps:

1. Create a new ASP.NET MVC 4 application using the Internet Template

2. In your package manager console type the following command:

   enable-migrations
   

3. 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" });
           }
       }
   }
   

4. 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>
   

5. Run the migration in your package manager console:

   update-database -verbose
