Entity Framework SetInitializer and Seed Data - entity-framework-6

Question

Having difficulty figuring out why my database will not seed:
Here is what I have in my Global.asax code:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
AuthConfig.RegisterAuth();
Database.SetInitializer(new DataContextInitializer());
DataContext db = new DataContext();
db.Database.Initialize(true);
WebSecurity.InitializeDatabaseConnection("DataContext", "UserModels", "Id", "UserName", autoCreateTables: true);
}
and here is the DataContextInitializer:
public class DataContextInitializer : CreateDatabaseIfNotExists<DataContext>
{
protected override void Seed(DataContext context)
{
if (!WebSecurity.Initialized)
{
WebSecurity.InitializeDatabaseConnection("DataContext", "UserModels", "Id", "UserName", autoCreateTables: true);
WebSecurity.CreateUserAndAccount("admin", "12345");
}
var roles = (SimpleRoleProvider)Roles.Provider;
var membership = (SimpleMembershipProvider)Membership.Provider;
if (!roles.RoleExists("admin"))
{
roles.CreateRole("admin");
}
if (membership.GetUser("admin", false) == null)
{
membership.CreateUserAndAccount("admin", "12345");
}
if (!roles.GetRolesForUser("admin").Contains("admin"))
{
roles.AddUsersToRoles(new[] { "admin" }, new[] { "admin" });
}
}
}
While debugging, the SqlException that I get is "There is already an object named ... in the database." Any idea why this would occur?

Answer 1

These are the steps I took:
Copied seed logic to the Migrations Configuration.cs file.
Excluded an old migration from the project
Within package console manager performed add-migration and gave it a name
Then ran update-database -verbose -force AFTER making sure that WebMatrix.WebData reference properties had 'CopyLocal = true'
I hope this helps someone.
