DbMigrator.GetPendingMigrations（）始终为空 [英] DbMigrator.GetPendingMigrations() always empty

问题描述

我正在使用 DbMigrator 类来获取挂起的迁移列表。由于某些原因，即使有待处理的迁移，它也不会返回任何项目。我错过了一步吗？

I'm using the DbMigrator class to get a list of pending migrations. For some reason it returns no items even though there are pending migrations. Am i missing a step?

var configuration = new Migrations.Configuration();
configuration.TargetDatabase = new DbConnectionInfo("MyDatabase");

var migrator = new DbMigrator(configuration);
var migs = migrator.GetPendingMigrations().ToList();
Console.WriteLine(migrator.GetPendingMigrations().ToString());

我以为可能是连接字符串，但有趣的是 migrator。 GetDatabaseMigrations（）返回已应用于db的正确迁移列表。

I thought it might be the connection string but what's interesting is that migrator.GetDatabaseMigrations() returns the correct list of migrations already applied to the db.

推荐答案

对我来说，原因是我正在不同的大会工作。在这种情况下，您需要指定包含迁移的程序集和命名空间：

The same happened to me and the reason was that I was working in a different assembly. In that case, you need to specify the assembly and namespace that contains your migrations:

config.MigrationsAssembly = Assembly.GetAssembly(typeof([One of your migration classes]));
config.MigrationsNamespace = "[Namespace containing your migrations]";
