Question

当我右键单击.EDMX文件并单击Generate Database From Model时，由于表名，生成的脚本显然是错误的。它生成的是以下脚本。请注意DROP TABLE部分与CREATE TABLE部分中的表名称。

为什么这不一致？

这显然不是可重复使用的脚本。我创建的是一个名为“Address”的实体和一个名为“Company”的实体等（所有单数）。 EntitySet名称是复数。 “Pluralize New Objects”布尔值也不会改变它。这是什么交易？

对于它的价值，我最初通过将EDMX指向具有非复数名称的表的数据库来生成EDMX，现在我已经做了一些更改，我想回到另一个方向。因为db-first和model-first模型在所有场景中都不是理想的，所以我希望可以选择前后移动。我可以控制以确保多个人都不会出现合并问题。方式同时。

我一直无法找到这个问题的答案。另外，我在重新解决这个问题时遇到了一些问题，我不会从数据库优先到模型优先的场景来回。因此，我只是假设来回引起了问题，并且让EF通过是一个糟糕的情况。
