On loading my ASP.NET app/site, I get this err msg: "An exception has been encountered. This may be caused by an extension."
然后说要查看此文件:
C:\ Users \ Clay \ AppData \ Roaming \ Microsoft \ VisualStudio \ 11.0 \ ActivityLog.xml
C:\Users\Clay\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml
...在其中，我确实找到了可能与问题有关的三个条目，但它们对我来说是希腊语".由于它们的庞大性，我在这里只包括第一个:

推荐答案
此错误通常是由缓存的元数据损坏引起的.我不知道为什么会这样，但是清除缓存通常会使Visual Studio恢复工作状态:
This error is often caused by a corruption in the cached metadata. Why this occurs I do not know, but clearing the cache will usually return Visual Studio to working order:
然后，当您安装了Visual Studio更新1,2,3或4并具有针对较旧版本构建的其他Visual Studio部件(例如Web工具)时，也会发生此异常.将它们升级到最新版本通常也有很多帮助:
And then this exception will also occur when you have installed Visual Studio update 1,2,3 or 4 and have other visual studio parts (like the web tools) that were built against an older version. Upgrading them to the latest version usually also helps quite a bit:
