[Entity Framework] Revert the database to specified migration.
[Entity Framework] Re-scaffold migration file.

對於初期沒有設計好Model的情況下, 已經add的migration並且已經update到db中之後可以通過下列命令達到重新編輯之前add的migration, 並且不會為你的項目新增migration文件.
比如我的項目已經有如下migration結構:

其中對於201901170814382_AddSlotManagement的migration,由於model模型變了我希望重新生成關於這個功能的migration.

• 首先將migration revert回到上一個migration

PM> Update-Database -TargetMigration 201901160836219_AddRelevanceModels
Specify the '-Verbose' flag to view the SQL statements being applied to the target database.
Reverting migrations: [201901170814382_AddSlotManagement].
Reverting explicit migration: 201901170814382_AddSlotManagement.
 

• 然後重新執行add migration.記住名字一致和加上-Force參數

PM> Add-Migration 201901170814382_AddSlotManagement
Re-scaffolding migration '201901170814382_AddSlotManagement'.
Only the Designer Code for migration '201901170814382_AddSlotManagement' was re-scaffolded. To re-scaffold the entire migration, use the -Force parameter.
PM> Add-Migration 201901170814382_AddSlotManagement -Force
Re-scaffolding migration '201901170814382_AddSlotManagement'.
