【问题描述】：

我有一个 asp.net MVC Code 第一个项目。 当我在 Nuget 控制台中运行此命令时：

“更新数据库”

它返回此错误：

    PM> update-database
Applying migration '20180623170538_natinalCode'.
System.InvalidOperationException: The annotation 'SqlServer:Include' was not found. Ensure that the annotation has been added.

这个项目不是核心......

我该怎么办？

感谢您的回复...

【问题讨论】：

你把'SqlServer:Include'添加到哪里了？

@LinkedListT 我没有在我的项目中找到“SqlServer:Include”。

您可以将更改后的模型也添加到问题中吗？！

【参考方案1】：

将 Microsoft.EntityFrameworkCore 、Microsoft.EntityFrameworkCore.SqlServer 和 Microsoft.EntityFrameworkCore.Tools 更新到 2.2.0 或更高版本:)
