Visual Studio 2017错误地认为安装了EF 6

Question

我将我的ASP.NET Core,EF Core类库解决方案升级到Visual Studio 2017.

但是,当我想运行Add-Migration等迁移命令时,我收到以下警告.

实体框架核心和实体框架6都已安装.实体框架核心工具正在运行.为Entity Framework 6使用'EntityFramework\Update-Database'.

但是我没有安装EF 6

我的csproj

    ...

如果您以前在VS中打开了EF6项目,则会发生这种情况.要卸载EF6,可以使用以下命令.

Remove-Module EntityFramework
