Ошибка миграции Entity Framework Core с использованием UseInMemoryDatabase

Я пытаюсь разделить свою Entity Framework и Identity на другую библиотеку, но я не могу выполнять миграции, когда использую builder.UseInMemoryDatabase(connectionString);.

Я могу выполнять миграции, когда меняю его на builder.UseSqlServer(connectionString);, но мне нужно использовать UseInMemoryDatabase.

Вот ошибка, когда я пытаюсь добавить миграцию:

Unable to resolve service for type Microsoft.EntityFrameworkCore.Migrations.IMigrator'. This is often because no database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions object in its constructor and passes it to the base constructor for DbContext.`

Код:

using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.EntityFrameworkCore.InMemory;
using Microsoft.Extensions.Configuration;
using System;
using System.IO;

namespace ClassLibrary1
{
    public class ApplicationUser : IdentityUser
    {
    }

    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            //modelBuilder.ApplyConfigurationsFromAssembly(typeof(ApplicationDbContext).Assembly);
            base.OnModelCreating(modelBuilder);
        }
    }

    public class ApplicationDbContextFactory : IDesignTimeDbContextFactory<ApplicationDbContext>
    {
        public ApplicationDbContextFactory()
        {
        }

        public ApplicationDbContext CreateDbContext(string[] args)
        {
            IConfigurationRoot configuration = new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("appsettings.json")
                .Build();

            var builder = new DbContextOptionsBuilder<ApplicationDbContext>();
            var connectionString = configuration.GetConnectionString("DefaultConnection");
            builder.UseInMemoryDatabase(connectionString);

            return new ApplicationDbContext(builder.Options);
        }
    }
}

и это ссылка

<ItemGroup>
    <PackageReference Include = "Microsoft.AspNetCore.App" />
    <PackageReference Include = "Microsoft.AspNetCore.Razor.Design" Version = "2.2.0" PrivateAssets = "All" />
    <PackageReference Include = "Microsoft.EntityFrameworkCore.InMemory" Version = "2.2.1" />
</ItemGroup>

но using Microsoft.EntityFrameworkCore.InMemory; - это неиспользуемое пространство имен.
