VS 2017（バージョン15.5）で新しいASP.NETコア2 MVCプロジェクトを作成し、ユーザーIDタイプをstringからGuidに変更しました）ユーザーに名前を付け、私のモデルを追加し、その後Entity Framework - オブジェクト 'PK_AspNetUserTokens'が 'UserId'列に依存しています
Add-Migration Init
Update-Database
が、それはエラーを生成し、データベースが作成されません。
public class ApplicationDbContext : IdentityDbContext<User, IdentityRole<Guid>, Guid>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
public DbSet<TvShow> TvShows { get; set; }
public DbSet<Episode> Episodes { get; set; }
public DbSet<Subscription> Subscriptions { get; set; }
public DbSet<Notification> Notifications { get; set; }
public DbSet<Genre> Genres { get; set; }
public DbSet<TvShowGenre> TvShowGenre { get; set; }
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
builder.Entity<Subscription>()
.HasKey(c => new { c.TvShowId, c.UserId });
builder.Entity<TvShowGenre>()
.HasKey(c => new { c.TvShowId, c.GenreId });
}
}
はここに私のマイグレーションクラスです（のみアップ法）：
