Windows Universal 8.1中的SQlite繁忙错误

Question

我的通用8.1应用程序中有SQlite。当我运行Windows 8.1应用程序时，它运行良好但是当我运行我的Windows手机应用程序时，我得到错误SQlite忙 这是我的代码：

private async void getSQLiteDataBase()
    {
        SQLiteAsyncConnection conn;
        conn = new SQLiteAsyncConnection("Setting.db");
        var ListIndex = await conn.Table<SettingTable>().Where(x => x.Name == "ColorSettingIndex").FirstOrDefaultAsync();
        var AlertPercent = await conn.Table<SettingTable>().Where(x => x.Name == "DataPlanAlertPercent").FirstOrDefaultAsync();
        var UpdateTimeIndex = await conn.Table<SettingTable>().Where(x => x.Name == "UpdateTimeIndex").FirstOrDefaultAsync();
        var NotificationIsEnabled = await conn.Table<SettingTable>().Where(x => x.Name == "NotificationIsEnabled").FirstOrDefaultAsync();
        var FirstNotification = await conn.Table<SettingTable>().Where(x => x.Name == "FirstNotification").FirstOrDefaultAsync();
        var SecondNotification = await conn.Table<SettingTable>().Where(x => x.Name == "SecondNotification").FirstOrDefaultAsync();
        var ThirdNotification = await conn.Table<SettingTable>().Where(x => x.Name == "ThirdNotification").FirstOrDefaultAsync();
        var TilesIsEnabled = await conn.Table<SettingTable>().Where(x => x.Name == "TilesIsEnabled").FirstOrDefaultAsync();

        if (ListIndex != null && AlertPercent != null && UpdateTimeIndex != null &&
            NotificationIsEnabled != null && FirstNotification != null 
            && SecondNotification != null && ThirdNotification != null && TilesIsEnabled != null)
        {
        ....
        }
    }

有可能帮助我吗？ 注意：我之前搜索过，发现我必须关闭数据库但是在Windows通用8.1上没有关闭我的数据库的属性。我在Windows上看到了SQlite的例子，他们没有关闭数据库的任何代码 我很抱歉英语不好 谢谢。
