Question

我最近更新了Visual Studio 2015社区，以包含Build 10586的SDK更新。

更新后，设计师已停止工作。最初在加载时，它要求提升访问权限以修复其安装的文件夹的某些权限或此类效果。但是我已经尝试了互联网上提供的一些修复，除了再次安装干净。

这是一个新的Blank Solution.的screeshot 实际的错误消息是

An Unhandled Exception has occurred

以下详细信息

System.NullReferenceException

如何让设计师再次工作？

Answer 1

由于我实际上找不到问题，因此临时解决方案是重新安装Visual Studio。不只是卸载并重新安装，而是一个干净的安装。有一些命令可以与安装程序一起使用，以完全删除驱动器上的任何残留物。
