我正在将经典的asp站点从Windows 2003 IIS 6 .net framework 1.1迁移到Windows 2008 32位IIS7 .net framework 2.0。我在装配装载时面临一些奇怪的问题。
有一组用C＃1.1编写的Com可调用包装器dll，这些dll使用在GAC中注册的dll（IConfigSectionHandler实现）。
Com callable wrapper无法加载此gac dll和fusion日志说;
*** Assembly Binder Log Entry (3/30/2015 @ 6:22:28 AM) *** The operation failed. Bind result: hr = 0x80070002. The system cannot find the file specified.

如果我把这个dll放到c：/ windows / system32 / inetsrv，它会在第二次尝试时加载。（如果我在第一次失败时刷新网站）
Com可调用包装器也在第二次尝试时加载，它也以相同的方式搜索Com可调用包装器，并且第一次无法加载。
为什么CLR在c：/ windows / system32 / inetsrv中搜索Com可调用包装器以及为什么GAC注册的dll也会在同一位置搜索。
任何想法
