有人可以帮助我写正确的代码DeleteBehavior.ClientCascade请.我有两个类Account和Schedule定义如下（Account可以有许多Schedule对象）：

public class Account : IdentityUser
        { 
            public string Title { get; set; }
            public string FirstName { get; set; }
            public string LastName { get; set; }
    
            public List<Schedule> Schedules { get; set; }
        }
        public class Schedule
        {
                public string AccountAccountId { get; set; }
                public int ScheduleId { get; set; }
                public DateTime Date { get; set; }
        }

... and the context

     public class DataContext : IdentityDbContext<Account>
        {
            public DbSet<Account> Accounts { get; set; }
            public DbSet<Schedule> Schedules { get; set; }
            public DataContext(IConfiguration configuration, DbContextOptions options) : base(options)
            {
                Configuration = configuration;
            }
    
            protected override void OnConfiguring(DbContextOptionsBuilder options)
            {
                // connect to sqlite database
                options.UseSqlite(Configuration.GetConnectionString("WebApiDatabase"));
            }
            protected override void OnModelCreating(ModelBuilder modelBuilder)
            {
                base.OnModelCreating(modelBuilder);
                //modelBuilder.Entity<Account>().HasMany(e => e.RefreshTokens).WithOne(e => e.Account).IsRequired();
    
                modelBuilder.Entity<Schedule>()
                .HasOne(b => b.Account)
                .HasMany(a => a.Schedules) <--- Error
                .OnDelete(DeleteBehavior.ClientCascade); <--- Error
            }
        }

字符串
我正在关注这篇文章link，但在尝试执行以下操作时，我的DataContext出现错误：

modelBuilder.Entity<Schedule>()
        .HasOne(b => b.Account)<--- error
        .HasMany(a => a.Schedules) 
        .OnDelete(DeleteBehavior.ClientCascade);
