搞定了，用了异步方法 正常了，感谢大大

您试试看用异步方法 await messageHandler.ExecuteAsync();是否会有同样的问题？
另外看一下启动代码的配置是否是严格按照Demo每一行都对照写了（可选的除外）。

这是messageHandler.Execute()报的错

 此异常最初是在此调用堆栈中引发的:

   [外部代码]

这个错误是在var messageHandler = new WorkCustomMessageHandler(Request.GetRequestMemoryStream(), postModel, maxRecordCount);这行就报了

.net 5.0用的是.net standard 2.1，完全兼容的。

您能跟踪到具体抛错的某一行代码吗？
