entity framework - EF6 Beta1 - db.Database.CreateIfNotExists(); doesn't create the database anymore after enabling the migration -

db.database.createifnotexists(); doesn't create database anymore , return true after enabling migration. don't see mentioned in release node well. bug?

note both automaticmigrationsenabled = true or false not working after "enable-migrations" in nuget console.

public void testmethod1() {         //using (var db = new hive.models.hivedbcontext()) {         using (var db = new testdbcontext()) {             var returnvalue = db.database.createifnotexists();              console.writeline(returnvalue);         }     }  public class testdbcontext : dbcontext {  }  internal sealed class configuration : dbmigrationsconfiguration<unittestproject1.testdbcontext> {     public configuration()     {         automaticmigrationsenabled = true;     }      protected override void seed(unittestproject1.testdbcontext context)     {         //  method called after migrating latest version.          //  can use dbset<t>.addorupdate() helper extension method          //  avoid creating duplicate seed data. e.g.         //         //    context.people.addorupdate(         //      p => p.fullname,         //      new person { fullname = "andrew peters" },         //      new person { fullname = "brice lambson" },         //      new person { fullname = "rowan miller" }         //    );         //     } }
