NServiceBus教程演示失败

Question

我开始学NServiceBus了。

我读到的第一件事是--我们展示了NServiceBus如何保证可靠性和可扩展性--，OK :)

从RetailDemo网站https://docs.particular.net/tutorials/quickstart/下载NServiceBus教程解决方案

运行它，它打开3个控制台应用程序ClientUI，销售，计费。它应该从ClinetUI向销售和计费发送信息。

然而，这个销售应用程序在这个细节上失败了(下一次甚至刚开始的时候也不再起作用)：

我想关键的原因是

问题-出什么事了？访问不被拒绝，任何文件都不保存此文件夹或文件。

如果他们的演示解决方案失败了，我能做些什么来继续学习这个框架呢？

Answer 1

它看起来很好用。

您在堆栈跟踪中看到的异常来自NServiceBus.DirectoryBasedTransaction.Commit()，并且是由Directory.Move()引起的。这是一个文件系统调用，它明确表示对.pending\c687e34a-4a0e-405a-bce2-25515b419778的访问被拒绝。

其原因可能各不相同。可能是上一次运行失败，文件夹/文件被锁定。您可以使用像Microsoft/SysInternals进程资源管理器这样的工具来查找导致锁定的进程。也可以在另一台机器上试用。
