这件事发生在我身上两次。一旦我的开发者许可证到期并提示我续订，我的 Visual Studio 设计器就开始崩溃，当我尝试加载任何 xmal 时，我会收到以下异常:
System.Runtime.InteropServices.COMException
The application cannot be started. Try reinstalling the application to fix the problem. (Exception from HRESULT: 0x80073CFC)

我已经尝试了很多方法来找到问题的解决方案，但没有任何效果，唯一的出路就是重新安装 Windows 并重新安装 Visual Studio。
最佳答案
尝试清除 Visual Studio 和 Team Foundation 服务器(如果适用)缓存。我知道这听起来很奇怪，但我的团队都经历了一个非常相似的问题，这是唯一一致有效的方法(除了完全重新安装)。
删除这些位置中的所有文件:
TFS 缓存:C:\Users[用户名]\AppData\Local\Microsoft\Team Foundation[版本]\Cache
一个可能的 VS 缓存位置:c:\Users\\AppData\Local\Temp\VWDCache
连接问题可能适用，也可能不适用，只是表明 VS 加载的项目的缓存版本可能与您的情况有冲突的许可证信息:https://connect.microsoft.com/VisualStudio/feedback/details/758523/visual-studio-2012-reloads-a-cached-version-of-an-edited-csproj-file
