我已经确认：

InnVue.BOA.RoomControl.dll 确实是 64 位 dll

InnVue.BOA.RoomControl.dll 引用的程序集也被主项目引用。

有没有什么方法可以准确地找到问题所在？堆栈跟踪中提供的信息不是很明显。

Answer 1

测试你的程序集引用的简单测试，如果它已被正确添加到您的项目中，copy local 是真的。 尝试将 release 构建部署到您的 本地 IIS 并尝试运行您的项目。您的应用程序可能由于缺少程序集而无法运行，请在返回之前继续修复它并打包您的 Web 应用程序以在 Azure 上对其进行测试。

另外，我使用程序集绑定日志查看器，它可以准确地告诉您 GAC 或您的 bin 目录中不存在的缺失程序集是什么。
