Database Migrations happen at Design-Time, not at Runtime. So you have to provide your IDE with a way to create a DbContext without starting the actual function. One way would be to implement a Design Time Factory as described in the Official Documentation. With that class created, the command Add-Migration automatically finds that class and executes CreateDbContext, which then provides the context for the migration.
