code首先迁移在SQL Azure中 - 表没有一个聚集索引不支持 [英] Code First Migrations in SQL Azure - Tables without a clustered index are not supported

问题描述

我似乎无法让我的code-首先迁移创建我的SQL Azure数据库。

I can't seem to get my Code-First Migration to create my SQL Azure database.

它使抱怨SQL Azure中缺乏对表支持，而聚集索引，我不能找到周围一个方法来创建我的数据库。

It keeps complaining about SQL Azure's lack of support for tables without clustered indexes and I cant find a way around to create my database.

注意：我用 CreateDatabaseIfNotExists 以创建的变化对第一次创建数据库跟踪表，因为显然 DropCreateDatabaseIfModelChanges 为您没有做到这一点。

Note: I'm using CreateDatabaseIfNotExists to create the change tracking tables on the first time database creation because apparently DropCreateDatabaseIfModelChanges doesn't do that for you

    public partial class IUnityDbContext : DbContext
    {
        public IUnityDbContext()
            : base("Name=IUnityDbContext")
        {
            Database.SetInitializer(new CreateDatabaseIfNotExists<IUnityDbContext>()); 
            //Database.SetInitializer(new DropCreateDatabaseIfModelChanges<IUnityDbContext>());
        }

        public DbSet<User> Users { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Configurations.Add(new UserMap());

            base.OnModelCreating(modelBuilder);
        }
    }




    public partial class Initial : DbMigration
    {
        public override void Up()
        {
            CreateTable(
                "dbo.Users",
                c => new {
                        ... 
                     }
            ).PrimaryKey(u => u.UserId, clustered: true);            
        }

        public override void Down()
        {
            DropTable("dbo.Users");
        }
    }

如果我尝试'更新数据库内我得到

If I try to `Update-Database I get

 Tables without a clustered index are not supported in this version of SQL Server. Please create a clustered index and try again.

不创建数据库。

更新：我从头开始，随后<一个href=\"http://geekswithblogs.net/michelotti/archive/2012/11/13/enable-automatic-$c$c-first-migrations-on-sql-database-in-azure.aspx\"相对=nofollow>本指南启用自动迁移（划伤数据库，并开始与一个不存在的之一，所以我没有从初始迁移删除向上/向下code）

UPDATE: I started from scratch and followed this guide to enable Automatic Migrations (scratched the database and started with a non-existing one so I didn't have to remove the Up/Down code from the Initial migration)

我的成功创建数据库这个时候（没得到这个前远），但表不创建，我仍然得到同样的错误作为前约没有没有聚簇索引对表的支持。

This time my database was successfully created (Did not get this far before) but the tables are not created and I still get the same error as before about no support for tables without clustered indexes.

请指教

推荐答案

原来是在实体框架6-α3.我想我应该提到的错误。

Turns out to be a bug in Entity Framework 6 -Alpha 3. I guess I should've mentioned that.
