我已经确认：

InnVue.BOA.RoomControl.dll确实是64位dll

主项目也引用InnVue.BOA.RoomControl.dll引用的程序集。

有什么办法可以精确地找到中断的地方吗？ 堆栈跟踪中提供的信息不是很明显。

Answer 1

用于测试程序集引用（如果已将其正确添加到带有复制本地的项目中）的简单测试是正确的。 尝试将发布版本部署到本地IIS，然后尝试运行项目。 可能是由于缺少程序集而导致您的应用程序无法运行，请在继续操作之前对其进行修复，然后打包并打包Web应用程序以在Azure上对其进行测试。

另外，我使用了程序集绑定日志查看器 ，它将准确地告诉您GAC或bin目录中不存在的缺少程序集。
