System.InvalidOperationException was unhandledMessage: An unhandled exception of type 'System.InvalidOperationException' occurred in WindowsBase.dllAdditional information: Dispatcher processing has been suspended, but messages are still being processed.
选择调试器时下意识又选择Visual Studio 2013，但一想这样不是会再次crash？竟然顺利启动成功。如果再次运行Visual Studio 2013还是会直接crash。

执行devenv /resetsettings启动，一切正常。再次重新启动依然crash。
使用WinDbg启动Visual Studio 2013，查看完整的异常信息：
