我在类库项目的模型文件夹中创建了一个 EDMX 类型文件。在该类库项目中，我将其创建为具有 Controller 、模型、 View 的 MVC 项目。在该模型文件夹中，我创建了名为 Model1.EDMX 的 EDMX 文件。当我运行该项目时，会引发以下错误。我不知道为什么会这样。我的项目中只有一个 EDMX 文件。 错误是:

有什么问题吗..？ 请帮助我解决这个问题。 提前致谢。
最佳答案
我已经解决了这个问题。 我有两个类库项目，并且在这两个项目上创建了 EDMX 文件，它们也具有与 EDMX 自动生成的“PivotEntities”相同的实体容器名称。
For eg. the two library projects named as Nop.Plugin.settings and Nop.Plugin.admin.
Cause of the error:
1.我将 EDMX 添加到上述项目，然后添加 Nop.Plugin.settings 的 .dll 或将其引用添加到 MVC 主项目。
2.然后删除该项目的 dll (Nop.Plugin.Settings) 或其对主项目或启动项目的引用。
3.然后我添加了Nop.Plugin.admin项目的.dll或其对MVC主项目的引用。
4.当我运行Main Mvc项目时，它抛出错误。
Solution:
1.我进入 Main Mvc 项目并单击“显示所有文件”。
2.这样它就显示了引用中的隐藏文件，我在那里找到了 Nop.Plugin.settings.dll、Nop.Plugin.settings.pdb、Nop.Plugin.admin.dll 和 Nop.Plugin.admin.pdb 。 3.实际上我已经从启动MVC项目中删除了项目Nop.Plugin.Setttings的引用，但它仍然驻留在启动项目中，这导致了问题。
所以现在我只需要Nop.Plugin.admin项目的dll和pdb并且我删除了隐藏中的Nop.Plugin.settings.pdb和Nop.Plugin.settings.dll BIN 文件夹。 :)
关于asp.net-mvc-4 - 由于错误 : Schema specified is not valid. 错误 :0019 . ，如何使架构在 Entity Framework 中唯一。？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17102759/
