What is the equivalent of the -IgnoreChanges switch for entity-framework core in CLI?

Question

With Visual Studio one can run the command

Add-Migration InitialCreate -IgnoreChanges 

in the Package Manage Console when creating the firs

Answer 1

My project has an existing database and we wanted to use migrations, since we do not have IgnoreChanges in EFCore what i did was ran the command

Add-Migration -Name InitialMigration in the package manager console of visual studio, this created the InitialMigration.cs file for me

And then I commented out the code in the Up function in the InitialMigration.cs and ran the command update-database in the package manager console.

Doing this creates a table named dbo.__EFMigrationsHistory in your database which keeps a track of your migrations.

Later when you add or remove the column, just run the Add-Migration command which will create a new migration for you make sure you validate the Up and Down function both to make sure everything looks ok and is as expected.

Once you validate, run the update-database function which should run the new migration script for you.

For now this is how we went ahead with our implementation.

Answer 2

In the absence of any other way, one can empty the Up and Down method blocks of the migration of all code and run database update.

public partial class Initial : Migration
{
    protected override void Up(MigrationBuilder migrationBuilder)
    {

    }

    protected override void Down(MigrationBuilder migrationBuilder)
    {
    }
}
