Question

尝试将初始种子设置到我的实体数据库时，我收到了一个奇怪的引用错误。 The type name 'Models' does not exist in the type 'SetupSheet.Models.SetupSheet'我无法弄明白。我必须有这些参考文献：

using SetupSheet.Models;
using SetupSheet.Models.CollectionofTool;

用于TurningTool对象的定义属性。

Answer 1

是的，我有一个类型的SetupSheet。我改变了它，它不起作用。感谢Ivan Gritsenko。

奇怪的错误：当播种实体数据库时，类型名称'Models'在类型....中不存在
