エンティティフレームワークコアorderby guidが正しく注文できない

Question

私は、リレーショナルデータベースとその注文ではなく、EFコアのGuidで注文しようとしています。私が間違っていることや、これがEFコアで問題になることはありますか？

namespace TestName 
{ 
    public class BoxDbContext : DbContext 
    { 
     public BoxDbContext(
      DbContextOptions<BoxDbContext> options) : base(options) 
     { 
     } 

     protected override void OnModelCreating(ModelBuilder modelBuilder) 
     { 
      modelBuilder.Entity<Box>().HasKey(x => x.Id); 
      modelBuilder.Entity<Box>().Property(t => t.Id).ValueGeneratedOnAdd(); 
      base.OnModelCreating(modelBuilder); 
     } 
    } 

    public class Box 
    { 
     public Guid Id { get; set; } 
     public Guid SubId { get; set; } 
    } 

    [TestFixture] 
    public class TestClass 
    { 
     private SqliteConnection SqliteConnection { get; set; } 

     private DbContextOptions<BoxDbContext> Options => new DbContextOptionsBuilder<BoxDbContext>() 
      .UseSqlite(SqliteConnection) 
      .EnableSensitiveDataLogging() 
      .Options; 

     private DbContext GetDbContext() 
     { 
      BoxDbContext dbContext = new BoxDbContext(Options); 
      dbContext.Database.EnsureCreated(); 
      return dbContext; 
     } 

     [SetUp]

      }; 
      SqliteConnection = new SqliteConnection(sqliteConnectionStringBuilder.ToString()); 
      SqliteConnection.Open(); 
     }

       { 
        dbContext.Set<Box>().Add(new Box {SubId = subId}); 
       } 
       await dbContext.SaveChangesAsync(); 
      } 

      IList<Box> boxs; 
      using (DbContext approvalsDbContext = GetDbContext()) 
      { 
       boxs = await approvalsDbContext 
        .Set<Box>() 
        .OrderByDescending(x => x.SubId) 
        .ToListAsync(); 
      } 

      Assert.That(boxs.Count, Is.EqualTo(subIds.Count)); 
      Assert.That(boxs.ToArray()[0].SubId, Is.EqualTo(subIds[1])); 
      Assert.That(boxs.ToArray()[1].SubId, Is.EqualTo(subIds[3])); 
      Assert.That(boxs.ToArray()[2].SubId, Is.EqualTo(subIds[0])); 
      Assert.That(boxs.ToArray()[3].SubId, Is.EqualTo(subIds[4])); 
      Assert.That(boxs.ToArray()[4].SubId, Is.EqualTo(subIds[2])); 
     } 
    } 
} 

おかげで、 クリス

は、だから私はそれにGUIDの表現を持っていないとして、これはSQLiteのために行動を意図していたと述べEFコアチームでこれを提起しました。 https://github.com/aspnet/EntityFrameworkCore/issues/10198#issuecomment-340930189
