У меня есть SQLServer 2016, и это приложение .Net Core.
Вот DbContext
namespace TrackTv
{
using Microsoft.EntityFrameworkCore;
using TrackTv.Models;
using TrackTv.Models.Joint;
public class TrackTvDbContext : DbContext
{
public DbSet<Actor> Actors { get; set; }
public DbSet<Episode> Episodes { get; set; }
public DbSet<Genre> Genres { get; set; }
public DbSet<Network> Networks { get; set; }
public DbSet<Show> Shows { get; set; }
public DbSet<User> Users { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder builder)
{
builder.UseSqlServer(@"Server=.;Database=TrackTvDb;Trusted_Connection=True;MultipleActiveResultSets=True;");
base.OnConfiguring(builder);
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
// ShowsUsers
modelBuilder.Entity<ShowsUsers>().HasKey(t => new
{
t.UserId,
t.ShowId
});
modelBuilder.Entity<ShowsUsers>().HasOne(t => t.User).WithMany(user => user.ShowsUsers).HasForeignKey(t => t.UserId);
modelBuilder.Entity<ShowsUsers>().HasOne(t => t.Show).WithMany(show => show.ShowsUsers).HasForeignKey(t => t.ShowId);
// ShowsActors
modelBuilder.Entity<ShowsActors>().HasKey(t => new
{
t.ShowId,
t.ActorId
});
modelBuilder.Entity<ShowsActors>().HasOne(t => t.Show).WithMany(show => show.ShowsActors).HasForeignKey(t => t.ShowId);
modelBuilder.Entity<ShowsActors>().HasOne(t => t.Actor).WithMany(actor => actor.ShowsActors).HasForeignKey(t => t.ActorId);
// ShowsGenres
modelBuilder.Entity<ShowsGenres>().HasKey(t => new
{
t.ShowId,
t.GenreId
});

modelBuilder.Entity<ShowsGenres>().HasOne(t => t.Genre).WithMany(genre => genre.ShowsGenres).HasForeignKey(t => t.GenreId);
}
}
}

Я могу войти в систему с помощью Management Studio следующим образом:
У меня есть несколько других рабочих.СЕТЕВЫЕ приложения, которые обращаются к этому экземпляру SQLServer с помощью EF6.
Ответ №1:
Не могли бы вы попробовать добавить встроенный атрибут безопасности в строку подключения?
builder.UseSqlServer(@"Server=.;Database=TrackTvDb;Trusted_Connection=True;MultipleActiveResultSets=True;Integrated Security=true");
Комментарии:
1. Нет,
Trusted_Connection=True
делает то, чтоIntegrated Security=true
делает. Я пробовал это.
