The command dotnet ef migrations add ${name} is used in the .NET Core framework for Entity Framework (EF) Core to add a new migration to the project.

Here's a breakdown of the command:

• dotnet is the command that runs .NET Core CLI (command-line interface) commands.
• ef is a subcommand specific to Entity Framework Core.
• migrations is the EF Core command to work with code-first database migrations.
• add is used to add a new migration to the project.
• ${name} is a placeholder for the name you provide. It should be replaced with an actual name for the migration.

When you execute this command, EF Core will create a new migration file with the provided name. The migration file contains the changes needed to bring the database schema to the state defined by the project's data model.

After adding a migration, you typically use the dotnet ef database update command to apply the migration and update the database schema based on the changes defined in the migration file.
