当我在.EDMX文件中右键单击,然后单击Generate Database From Model时,由于表名称,产生的脚本显然是错误的。它生成的是以下脚本。请注意0​​部分中的表名与CREATE TABLE部分中的表名。EF4生成无效脚本

这是为什么不一致?

这显然不是一个可重复使用的脚本。我创建的是一个名为“Address”的实体和一个名为“Company”的实体等(都是单数形式)。 EntitySet名称被复数化。 “多重新对象”布尔值也不会改变这个。那么交易是什么?

对于它的价值,我最初生成EDMX的方法是将它指向一个具有非复数名称表的数据库,现在我已经做了一些更改,我想以其他方式返回。我希望可以选择来回切换,因为db-first和model-first模型在所有情况下都不是理想的,并且我有控制权确保不会有多人同时出现合并问题方式在同一时间。

我一直无法找到这个问题的答案。另外,我在重新创建这个问题时遇到了问题,我不会从DB优先到模型优先的情况。因此,我只是假设来回发生了问题,并且是通过EF来解决问题的一个不好的情况。
