如何解决如何使用托管身份从Visual Studio运行EF6代码优先迁移

我有一个系统管理的身份，可以在Azure中创建，并且可以通过Azure服务身份验证在Visual Studio 2019中进行调试，但是，当我从Package Manager控制台运行Update-Database时，我无法应用代码优先迁移除了以下例外。

正如我所说的，它在迁移之外的所有地方都有效，这使我认为Powershell无法找到dll的位置。我尝试从项目的build文件夹运行命令，但会抛出相同的异常。

  • EntityFramework 6.2
  • Microsoft.Azure.Services.AppAuthentication 1.5.0

还有其他配置需要完成吗？
