当我运行项目(F5)时,我在IDE中收到以下异常:
An unhandled exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

我没有注意到在没有调试器(CTRL + F5)的情况下运行时收到相同的异常。这是一个WPF项目,但在App_ctor执行之前发生异常,因此这是外部代码,我的应用程序代码没有开始执行。偶尔发生这种情况,有时它只发生一次,有时我会运行项目并在滚动中多次获得此消息。然后它不会弹出5-6次运行,然后再次启动。
任何人都知道为什么会这样?我刚刚安装了干净的W8.1 64位,VS2013和TFS 2013(虽然我遇到了与W8和VS2012相同的问题,但并不常见)。

此问题似乎在dot net framework update(4.5.2)中得到修复。 https://connect.microsoft.com/VisualStudio/feedback/details/819552/visual-studio-debugger-throws-accessviolationexception
