c# - System.ArgumentException：通过 Hangfire 任务调用 NServiceBus 时路径不是合法形式

问题描述

当我尝试通过 Hangfire 任务调用 NServiceBus/Rabbit MQ 时出现以下错误我尝试将 .NET Framework 版本从 4.5.2 更新到 4.6.1

不知道我在这里做错了什么？我不断收到此错误但是，当我在本地（通过测试项目）运行它时，消息已成功放置在服务总线上（我能够在服务端点上看到它）

解决方案

我们通过将 NService Bus 文件（包括 DLL）放在 Hangfire 任务所在的同一台服务器上解决了这个问题，并在 Hangfire 任务解决方案中添加了对 NService Bus 的引用
