ef core2.2 mysql迁移问题

前段时间，遇到的是ef core mysql迁移的时候，bool类型会自动yingsheweishort的问题，需要手动更正一下
今天测试的时候，遇到了MySQL数据表修改后迁移的问题。

问题详情如下
System.NotImplementedException: The method or operation is not implemented.

at Microsoft.EntityFrameworkCore.Migrations.MigrationsSqlGenerator.Generate(RenameColumnOperation operation, IModel model, MigrationCommandListBuilder builder)

at Microsoft.EntityFrameworkCore.Migrations.MigrationsSqlGenerator.Generate(MigrationOperation operation, IModel model, MigrationCommandListBuilder builder)

at Microsoft.EntityFrameworkCore.Migrations.MigrationsSqlGenerator.Generate(IReadOnlyList`1 operations, IModel model)

at Microsoft.EntityFrameworkCore.Migrations.Internal.Migrator.GenerateUpSql(Migration migration)

at Microsoft.EntityFrameworkCore.Migrations.Internal.Migrator.Migrate(String targetMigration)

at Microsoft.EntityFrameworkCore.Design.Internal.MigrationsOperations.UpdateDatabase(String targetMigration, String contextType)

at Microsoft.EntityFrameworkCore.Design.OperationExecutor.UpdateDatabase.<>c__DisplayClass0_1.<.ctor>b__0()

at Microsoft.EntityFrameworkCore.Design.OperationExecutor.OperationBase.Execute(Action action)

The method or operation is not implemented.

然后一顿搜索，发现当前的mysql修改迁移确实有BUG，但是新增表和新增字段是没有问题的。
所有，修改属性的时候，只能是将表重建才可以

或者更换polem的那个包可以实现迁移
