MVC4 EF code first database initialization incomplete in production

I have created a website using MVC4 and I updated the framework to 4.5.1.

Everything works perfectly in development phase. I have enabled the migration with entity framework code first and created a migration "Init".

I have simple membership. When I drop my local database and launch the application, I have all tables perfectly created.

However, when I deploy (FTP) on the production server, I only have a subset of tables.

This is what is done in Global.asax.cs after I tried this

internal void Application_Start() { MvcHandler.DisableMvcResponseHeader = true; Database.SetInitializer( new MigrateDatabaseToLatestVersion<GlobalDbContext, Migrations.Configuration>("DefaultConnection")); AreaRegistration.RegisterAllAreas(); GlobalConfiguration.Configure(WebApiConfig.Register); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); AuthConfig.RegisterAuth(); using (var context = new GlobalDbContext()) { if (!context.Database.Exists()) { // Register the SimpleMembership database without Entity Framework migration schema //((IObjectContextAdapter)context).ObjectContext.CreateDatabase(); context.Database.Create(); } ////context.Database.Initialize(true); //context.Database.Delete(); //context.Database.Create(); } WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "Username", autoCreateTables: true); } 

Apparently, It's context.Database.Create(); that behaves differently in production.

I already have deployed a full MVC4 application and a full MVC5 application. But it is the first time I deploy a MVC4 application updated to .net 4.5.1 (I don't know if that helps).

Any idea?

Edit (add DbContext sample)

public class GlobalDbContext : DbContext { public GlobalDbContext() : base("DefaultConnection") { }

 protected override void OnModelCreating(DbModelBuilder modelBuilder) { Database.SetInitializer<GlobalDbContext> ( new CreateDatabaseIfNotExists<GlobalDbContext>() ); //using model builder here base.OnModelCreating(modelBuilder); } public DbSet<Patient> dbSet1 { get; set; } [***] }
