c# – BulkInsert – 空间’CSSpace’没有关联的集合

在使用复杂的数据模型失败后,我回到了一个简单的测试人员.
我正在尝试插入的实体如下所示：
Id – Int
名称 – 字符串

使用VS生成实体,然后使用VS内置功能跟踪数据库.
我尝试了两个EF,4和5.没有工作.例外是：

空间’CSSpace’没有相关的集合.

两种数据模型的例外情况相同.

据我所知,我使用了所有依赖项.

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);
}

stacktrace是这样的：
