运行 .NET webapp 时,我收到了一个我不知道的 EventLog 错误。
该应用程序基本上从数据库读取,然后从磁盘读取(读取文件大小,然后写回数据库)。
我已经在我的工作站(IISExpress)和我们的其他服务器(带有 IIS7 的 Windows 2008)上启动并运行了该应用程序,没有任何问题
但是当我使用 IIS6 在我们的 2003 R2 服务器上运行它时,我得到了一些奇怪的行为。IIS 应用程序启动并没有报告任何错误,但是当我尝试访问该网页时,我得到一个“服务器应用程序不可用”,并且服务器上的 EventLog 给了我这个转储:
Event Type: Error

该应用程序继续在 IIS 中运行。这个 IIS 还托管了一大堆其他站点,没有任何问题。是的,该应用程序设置为在 .NET 4 上运行,并且服务器托管其他 .NET 4 应用程序也没有任何问题。
据我所知,它无法加载 System.Web 程序集,但我不确定这怎么可能......
这是应用程序的 web.config:
