How to allow migration for a console application?

Question

When using asp.net core and ef core, I have no problem when invoking add-migration init. But when I apply the same approach on a console application below, I got an

Important: Don't name your assembly ef (or eF or Ef or EF) to avoid this exception.

After struggling several hours, I found the solution as follows:

using EFCore.Models;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.Extensions.Configuration;
using System.IO;

namespace EFCore
{
    class Program : IDesignTimeDbContextFactory<StudentContext>
    {
        public StudentContext CreateDbContext(string[] args)
        {
            var configurationBuilder = new ConfigurationBuilder()
              .SetBasePath(Directory.GetCurrentDirectory())
              .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

            IConfigurationRoot configuration = configurationBuilder.Build();
            string connectionString = configuration.GetConnectionString("Storage");

            DbContextOptionsBuilder<StudentContext> optionsBuilder = new DbContextOptionsBuilder<StudentContext>()
                .UseSqlite(connectionString);

            return new StudentContext(optionsBuilder.Options);
        }

        static void Main(string[] args)
        {
            Program p = new Program();

            using (StudentContext sc = p.CreateDbContext(null))
            {
                sc.Database.Migrate();

                sc.Students.AddRange
                (
                    new Student { Name = "Isaac Newton" },
                    new Student { Name = "C.F. Gauss" },
                    new Student { Name = "Albert Einstein" }
                );

                sc.SaveChanges();
            }
        }
    }
}

I hope it is also useful for others!
