Visual Studio 2012 设计器在开发人员许可证续订后崩溃

Question

碰巧是我两次。一旦我的开发人员许可证到期并提示我更新它，我的 Visual Studio 设计器就会开始崩溃，并且当我尝试加载任何 xmal 时出现以下异常：

System.Runtime.InteropServices.COMException
The application cannot be started. Try reinstalling the application to fix the problem. (Exception from HRESULT: 0x80073CFC)

我已经尝试了很多来找到问题的解决方案，但没有任何效果，唯一的出路是重新安装 Windows 并重新安装 Visual Studio。

Answer 1

尝试清除您的 Visual Studio 和 Team Foundation Server（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，这是唯一一直有效的事情（除了完全重新安装）。

删除这些位置的所有文件：

TFS 缓存：C:\Users[UserName]\AppData\Local\Microsoft\Team Foundation[Version]\Cache

一个可能的 VS 缓存位置：c:\Users\\AppData\Local\Temp\VWDCache

可能适用也可能不适用的连接问题，仅表明 VS 加载缓存的项目版本可能在您的情况下具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

类似的事情曾经发生在我身上。尝试清理项目，也就是清理项目文件夹中的 bin 和 obj 文件夹。
