EF 6.2.0 migrate.exe ERROR: Object reference not set to an instance of an object

EF 6.2.0 migrate.exe ERROR: Object reference not set to an instance of an object

我正在设置 migrate.exe 到 运行 VSTS 发布期间的数据库迁移:
migrate.exe DataAccess.dll /connectionProviderName="System.Data.SqlClient" /connectionString="Data Source=SQLXXX\DEV01;Initial Catalog=XXXXX;Integrated Security=true;" /verbose 输出:

VERBOSE: Target database is: 'XXXXX' (DataSource: SQLXXX\DEV01, Provider: System.Data.SqlClient, Origin: Explicit).
No pending explicit migrations.
Running Seed method.
System.Data.Entity.Migrations.Design.ToolingException: Object reference not set to an instance of an object.
   at System.Data.Entity.Migrations.Design.ToolingFacade.Run(BaseRunner runner)
   at System.Data.Entity.Migrations.Console.Program.Run()
   at System.Data.Entity.Migrations.Console.Program.Main(String[] args)
ERROR: Object reference not set to an instance of an object.

我们在 Seed 方法中没有代码。 No pending explicit migrations 是预期的,但我们需要脚本无错误地完成,发布过程才能继续。如何修复此错误?

I raised this issue on EF6 GitHub

为了让它工作,我必须提供 /startupConfigurationFile 而不是 /connectionString。
