将xamarin与EF核心一起使用会产生SQLite错误

如何解决将xamarin与EF核心一起使用会产生SQLite错误

模型是 成员有很多玩家（一对多Relationshiphip） 玩家有很多运动 体育有很多球员 PlayerSports与玩家和体育之间的多对多关系

public class Member
{
    public int MemberId { get; set; }
    public string Code { get; set; }
    public double Payment { get; set; }
    public virtual List<Player> Players { get; set; }
}

public class Player
{
    public int PlayerId { get; set; }
    public string Name { get; set; }
    public double Payment { get; set; }
    public virtual ICollection<PlayerSport> PlayerSports { get; set; }
    public int MemberId { get; set; }
    public virtual Member Member { get; set; }
}

public class Sport
{
    public int SportId { get; set; }
    public string Name { get; set; }
    public string Type { get; set; }
    public double Price { get; set; }
    public virtual ICollection<PlayerSport> PlayerSports { get; set; }
}

public class PlayerSport
{
    public int PlayerId { get; set; }
    public int SportId { get; set; }
    public virtual Player Player { get; set; }
    public virtual Sport Sport { get; set; }
}

当成员被删除时，删除子级球员而不删除运动 删除播放器后，其父级成员和体育项目仍然相同

    public class AppContext : DbContext
    {
        public DbSet<Member> Members { get; set; }
        public DbSet<Player> Players { get; set; }
        public DbSet<Sport> Sports { get; set; }
        public DbSet<PlayerSport> PlayeRSSports { get; set; }

    public AppContext()
    {
        sqlitePCL.Batteries_V2.Init();

        this.Database.EnsureCreated();
    }
    
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<Member>()
            .HasMany<Player>(m => m.Players)
            .WithOne(p => p.Member)
            .HasForeignKey(p => p.MemberId)
            .OnDelete(DeleteBehavior.Cascade);

        modelBuilder.Entity<PlayerSport>()
            .HasKey(t => new { t.PlayerId,t.SportId });

        modelBuilder.Entity<PlayerSport>()
        .HasOne(ps => ps.Player)
        .WithMany(p => p.PlayerSports)
        .HasForeignKey(ps => ps.PlayerId);

        modelBuilder.Entity<PlayerSport>()
            .HasOne(ps => ps.Sport)
            .WithMany(s => s.PlayerSports)
            .HasForeignKey(ps => ps.SportId);
    }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        string dbPath = Path.Combine(FileSystem.AppDataDirectory,"members.db3");

        optionsBuilder
            .Usesqlite($"Filename={dbPath}");
    }
}

保存条目并调用SaveChangesAsync时出现错误
