Question

前几天我遇到了EF中最常见的问题之一，即批量插入。经过一些谷歌搜索，我发现了这个：http://efbulkinsert.codeplex.com/

在使用复杂数据模型失败后，我又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。

两种数据模型的异常相同。

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);
}

堆栈跟踪是这样的：

有什么想法吗？

这个库是为代码优先而制作的。我还没有完成数据库优先。

BulkInsert - 空间＆＃39; CSSpace＆＃39;没有相关的集合
