Visual Studio中遇到異常

所以，我使用Visual Studio 2010，並在過去一週我越來越從Visual Studio來了一條消息：「Visual Studio中遇到的異常，這可能由以下原因引起一個延伸。「Visual Studio中遇到異常

我ActivityLog.xml表明將這一情況記錄問題：

似乎沒有是導致此任何具體行動，有時會發生當我第一次火了VS，我離開後，有時我的桌子一會兒回來。另外，從日誌中，它似乎在加載Visual Studio CSS編輯包後立即發生。我安裝了MVC4，也許是與新的CSS問題（CSS3我覺得呢？）

不管怎麼說，只是不知道是否有人已經先運行到這一點，並有某種分辨率。

似乎有些VS延長可能會導致其崩潰。（你安裝任何擴展名爲最近還好嗎？）

嘗試在安全模式下運行VS診斷問題。

運行這個命令並檢查是否VS開始

devenv.exe /safemode

呀，可惜它仍然發生在安全模式下，同樣的錯誤 – sovemp

可能會嘗試修復/重新安裝VS ..這可能有助於..也可是你可以在這裏使用工具提交VS的錯誤.. http://blogs.msdn.com/b/visualstudio/archive/2012/06/20/the-visual-studio-2012-feedback-tool-a-better-way-to-submit-bugs.aspx – Amitd

是的，我想我最終會這樣做，它現在不會崩潰或什麼，只是更多的煩惱。 – sovemp

VS需要管理員previleges處理插件。所以右擊VS並點擊「作爲管理員運行」。它解決了我。嘗試一次。
