在过去的几个晚上，我一直在尝试将 MVC 解决方案上传到 Azure 或使用 Pirahna CMS 的带有 IIS 7.5 的 VM。

没有 DevExpress 可以正常上传，但是当我引用 DevExpress 时出现异常（见下文）。

我知道 Piranha CMS 使用 MEF，我想知道 DevExpress 是否也这样做并且它们发生冲突（大假设）。

例外：

Server Error in '/' Application.

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

我努力了

- 调试并遵循检索 LoadExceptions 的指南，但它们为空。

- 确保我引用的项目已构建“任何 cpu”

我已经使用相同的放置文件夹在本地设置了 IIS，但我遇到了一个不同的异常，我必须启用对 app_data/logs 的写入权限，这样做时站点在本地工作。我尝试在我的 IIS VM 上执行此操作，但没有效果。

任何人都可以就这个错误提供一些建议吗？

提前致谢。
