❔ I can't create migration

using Microsoft.EntityFrameworkCore;

public class ExampleDBContext : DbContext
{
    public DbSet<Product> Products { get; set; }
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer("Server=localhost,1433;Database=DenemeDB;User Id=Umut;Password=mypass
");
    }
}

public class Product
{
    public int Id { get; set; }
   

}
