Visual Studio中遇到异常

所以，我使用Visual Studio 2010，并在过去一周我越来越从Visual Studio来了一条消息：“Visual Studio中遇到的异常，这可能由以下原因引起一个延伸。“Visual Studio中遇到异常

我ActivityLog.xml表明将这一情况记录问题：

似乎没有是导致此任何具体行动，有时会发生当我第一次火了VS，我离开后，有时我的桌子一会儿回来。另外，从日志中，它似乎在加载Visual Studio CSS编辑包后立即发生。我安装了MVC4，也许是与新的CSS问题（CSS3我觉得呢？）

不管怎么说，只是不知道是否有人已经先运行到这一点，并有某种分辨率。

似乎有些VS延长可能会导致其崩溃。（你安装任何扩展名为最近还好吗？）

尝试在安全模式下运行VS诊断问题。

运行这个命令并检查是否VS开始

devenv.exe /safemode

呀，可惜它仍然发生在安全模式下，同样的错误 – sovemp

可能会尝试修复/重新安装VS ..这可能有助于..也可是你可以在这里使用工具提交VS的错误.. 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，我想我最终会这样做，它现在不会崩溃或什么，只是更多的烦恼。 – sovemp

VS需要管理员previleges处理插件。所以右击VS并点击“作为管理员运行”。它解决了我。尝试一次。
