c# - BulkInsert - 空间 'CSSpace' 没有关联的集合

Question

几天前，我遇到了 EF 中最著名的问题之一，即批量插入。经过一番谷歌搜索后，我发现了这个:http://efbulkinsert.codeplex.com/

在使用复杂的数据模型失败后，我回到了一个简单的测试器。我要插入的实体如下所示:Id - 整数名称 - 字符串

实体是使用 VS 生成的，然后使用 VS 内置功能跟随数据库。我尝试了 EF，4 和 5。都没有用。异常(exception)情况是:

空间“CSSSpace”没有关联的集合。

两个数据模型的异常是相同的。

据我所知，我使用了我必须使用的所有依赖项。

代码:

using (Model1Container ctx = new Model1Container())
{
    List<TestEntity> list = new List<TestEntity>();

    for (int i = 0; i < 10; i++)
    {
        TestEntity enti = ctx.TestEntitySet.Create();
        enti.Name = "stav" + i;
        list.Add(enti);
        ctx.TestEntitySet.Add(enti);
    }

    ctx.BulkInsert<TestEntity>(list);
}

堆栈跟踪是这样的:

有什么想法吗？

这个库是为代码优先而创建的。我还没有完成 DB-first。
