无法找到程序集"Microsoft.SqlServer.Types"版本10或更高版本

Question

我有个问题.我无法将迁移添加到我的ASP.NET WebAPI 2项目中.我收到错误:

"此提供程序无法使用空间类型和函数,因为无法找到程序集"Microsoft.SqlServer.Types"版本10或更高版本."

我知道有几个问题和答案,如:

• 在Azure上找不到"Microsoft.SqlServer.Types"版本10或更高版本
• 在ASP.NET中将字符串转换为DbGeometry时出现"空间类型和函数不可用"错误

但!问题是...

• 我已经安装了Microsoft.SqlServer.Types.
• 我已经将Global.asax配置为:SqlServerTypes.Utilities.LoadNativeAssemblies(Server.MapPath("〜/ bin"))到Application_Start中.
• 参考设置为本地副本> true.
• NuGet包都已更新.
• 我已经尝试降级并升级包.

当我尝试运行Add-Migration v002时,这是完整的错误:

System.InvalidOperationException:此提供程序无法使用空间类型和函数,因为无法找到程序集"Microsoft.SqlServer.Types"版本10或更高版本.

经过大量研究后,我刚从以下位置安装了"SQL Server 2012的Microsoft System CLR类型":
