            public DbSet<ReferenceFile> ReferenceFiles { get; set; }
            protected override void OnModelCreating(ModelBuilder modelBuilder)
            {
                base.OnModelCreating(modelBuilder);
                modelBuilder.Entity<Employee>()
                   .HasKey(t => new { t.EmployeeId });
    
                modelBuilder.Entity<ReferenceFile>()
                    .HasKey(t => new { t.Code,t.TableName,t.FieldName });
            }
