项目执行的时候出现错误

There is already an open DataReader associated with this Command which must be closed first.

可以尝试在连接字符串中，加上
MultipleActiveResultSets=true

具体的原因和方案，探究中

疑似发现aop事务存在问题

起初是在自己的项目里，使用aop事务出现了This SqlTransaction has completed; it is no longer usable.的问题，后发现是在services层调用多个Repository层方法时，可能在services方法未执行完成的情况下，提交了事务。
后下载了博主的源码。也发现了类似的问题。
1
这里访问第一个数据访问层方法
2
然后就进了aop，接着断点就开始乱跳
3
4
在访问第三个数据访问层方法之前，工作单元就会提交事务(实际上也可能直接跟着图2继续执行下去)
5
6
接着就会报This SqlTransaction has completed; it is no longer usable.的问题
但是在我的项目里数据库操作是会成功的，用的是mssql
怀疑是否有可能是拦截器和service层并行了导致的，因为都是异步方法。
感谢群主开源，对.Net社区做的贡献。

mysql +sqlsugar 时间类型的字段 SugarColumn 设置可空 c#的时间字段不是可空类型

环境：sqlsugar+mysql
[SugarColumn(ColumnName = "approval_time", ColumnDescription = "审核时间"**,IsNullable =true**)] public DateTime approval_time { get; set; }
加上特性IsNullable =true 但是 DateTime 没有加？实体查询的时候会导致程序崩溃！是奔溃！不是报错哦！ 如果改成

[SugarColumn(ColumnName = "approval_time", ColumnDescription = "审核时间"**,IsNullable =true**)] public DateTime? approval_time { get; set; }
就没有问题

关于本项目在并发中出现数据库连接closed的问题。

【用sqlsugr有时候会报Invalid operation. The connection is closed】

【说明】：就是在异步多并发的时候，sugar实例偶尔会出现连接异常，并不是很常见，如果并发达不到一千以上，不用担心这个问题。

【更正】：有人提到这个问题，多半是自己没有更新SqlSugar 5.0.10+版本，请不要使用之前的版本，还一直压测说报错。

如果还不行
【最后的方案】
1、或者每次访问仓储中每一个方法的时候，都new一个实例，这样实例就不会丢失了。比如把BaseRepository的_db换成一个获取实例方法，每次都new一个，或者ISqlsugarclient注入改成services.AddTransient(o =>。
但是这样不利于事务提交，所以我不建议这么操作。

2、当然好像在同步中没有这个问题，想省事儿，改成同步也行。

MD5 32算法修改

MD5Encrypt32
pwd = string.Concat(pwd, item.ToString("X"));
改成
pwd = string.Concat(pwd, item.ToString("X2"));

要保证32位

我在用JWT这步时报了一个错误

appsettings.json操作类 建议 

    static Appsettings()
    {
        string Path = "appsettings.json";
        if (Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") == "Development")
        {
            Path = "appsettings.Development.json";
        }

        Configuration = new ConfigurationBuilder()
        .Add(new JsonConfigurationSource { Path = Path, ReloadOnChange = true })//请注意要把当前appsetting.json 文件->右键->属性->复制到输出目录->始终复制
        .Build();
    }

增加环境变量的判断

发现LogAop存在无法记录异常信息的问题

if (typeof(Task).IsAssignableFrom(type))
{
var resultProperty = type.GetProperty("Result");
dataIntercept += ($"【执行完成结果】：{JsonConvert.SerializeObject(resultProperty.GetValue(invocation.ReturnValue))}");
}
else
{
dataIntercept += ($"【执行完成结果】：{invocation.ReturnValue}");
}

        Parallel.For(0, 1, e =>

            LogLock.OutSql2Log("AOPLog", new string[] { dataIntercept });
        });//多线程并行的for循环

netcore2.2分支下Blog.Core.Model/Seed/DBSeed.cs GitJsonFileFormat和GitJsonFileForma2 url不存在

https://github.com/anjoy8/Blog.Core/blob/netcore2.2/Blog.Core.Model/Seed/DBSeed.cs
该文件下的GitJsonFileFormat和GitJsonFileForma2 url不存在（gitee和github）都如此，导致无法自动初始化表数据。估计是大牛你忘记了url吧。

改为如下。具体大牛你再看下

请问 为何每个Repository(IUnitOfWork unitOfWork) 都要传递这个unitOfWork

XXXRepository通过反射加入容器，那这个 IUnitOfWork 肯定来源于容器依赖注入，IUnitOfWork 依赖于SqlSugarClient的ADO事务；这种传递是为何？也没见类内部使用啊。
如果想用跨方法事务，直接在构造方法注入即可，开启线程share，难道不传时，直接注入IUnitOfWork 会出问题？

项目在Seed Mysql 数据时候报错。

Quartz 任务是否 IsStart 问题

1，当应用程序部署在iis 中，iis应用程序池有回收机制，回收之后quartz会全部停止，此时TasksQz表里的IsStart 字段将不再准确，
建议使用以下代码判断启动状态
public async Task GetJobState(TaskJobInfo model)
{
JobKey jobKey = new JobKey(model.rowId.ToString(), model.jobGroup);
var triggers = (await _scheduler.Result.GetTriggersOfJob(jobKey)).FirstOrDefault();
if (triggers != null)
{
return await _scheduler.Result.GetTriggerState(triggers.Key);
}
return TriggerState.None;
}

2，建议将task 从主程序中剥离出来，单独部署

FromBody 方式 提交实体 IPLogMildd.cs 报错

楼主发现个错误，如下
测试代码
` public async Task Login([FromBody] LoginModel loginModel)
{

    return new JsonResult(new
            {
                success = false,
                message = "msg"
            });

}`
在 IPLogMildd.cs 报错 行 72
导致进不到方法中

autofac 组件在6.0版本出现注入失败问题

Castle.DynamicProxy.ProxyGenerationException: This is a DynamicProxy2 error: Target type for the proxy implements Castle.DynamicProxy.IProxyTargetAccessor which is a DynamicProxy infrastructure interface and you should never implement it yourself. Are you trying to proxy an existing proxy?

版本区别

master，NETcore2.2 有什么区别吗，master 是NETCore 2.2吗
