Final answer:
To revert a database to a previous migration in the Package Manager Console, use the 'Update-Database' command with the name of the target migration.
This command updates the database schema to match the migration specified. For reverting all migrations, the keyword '0' can be used.
Therefore, the correct answer is: option b) .Update-Database
Step-by-step explanation:
Update-Database command allows you to update the database to a specific migration by specifying the name of the migration you want to revert to as a parameter.
If no migration name is specified, it will revert to the last migration.
For example, if you have a migration named 'InitialCreate' and you want to revert the database back to this state, you would use the following command:
- Update-Database -Migration InitialCreate
If you want to revert to the state before any migrations were applied, you can use the special keyword '0':
- Update-Database -Migration 0
It's important to note that this will not remove the migrations from the project; it merely reverts the database to the state before the specified migration was applied. To remove a migration from the project, you would use the Remove-Migration command.
