Visual Studio 2012的设计器崩溃Windows Phone

我最近从VS2010切换到VS2012。即使重新安装SDK后，设计人员也会崩溃。Visual Studio 2012的设计器崩溃Windows Phone

以下异常被抛出：

我怎样才能解决这个问题？请注意，它在Blends中正常工作，并在VS中崩溃。

我知道你已经尝试重新安装，但似乎重新安装的顺序可能很重要 - http://stackoverflow.com/questions/13394092/windows-phone-8-error-on-fresh-application – keyboardP

我做了它以相同的顺序，但会尝试重新安装一切。 –

您需要更新Blend SDK的程序集版本。你可能引用了旧版本。 –

可能是this thread对您有帮助。您的环境中存在安装问题。

希望它有帮助。
