每次使用Entity Framework更新数据库时如何创建新迁移

Question

In my dbo.__MigrationHistory table from my Entity Framework database I have 3 entries:

201708082015111_InitialCreate 
201708082017162_Initial
201708082046380_AutomaticMigration

but in the project itself, I have just one migration file:

201708082017162_Initial.cs

I was thinking to delete the database and start over.

My main focus is how to create migration files each time I update the database from package console. For example, I create another model (therefore, another entity in my schema), so I want to run Update-Database and create a migration file in C# at the same time containing information about the updated schema (with the new table...).

因此，我通过应用以下程序使其工作： Add-Migration migx ，然后运行Update-Database -verbose然后，我检查了__MigrationHistory表，并注意到已应用201708082108002_migx。
