By default, EF Core keeps track of which migrations have been applied to the database by recording them in a table named
__EFMigrationsHistory. For various reasons, you may want to customize this table to better suit your needs.
Important
If you customize the Migrations history table after applying migrations, you are responsible for updating the existing table in the database.
You can change the schema and table name using the MigrationsHistoryTable() method in OnConfiguring() (or
ConfigureServices() on ASP.NET Core). Here is an example using the SQL Server EF Core provider.

To configure additional aspects of the table, override and replace the provider-specific
IHistoryRepository service. Here is an example of changing the MigrationId column name to Id on SQL Server.

SqlServerHistoryRepository is inside an internal namespace and may change in future releases.
