“提供程序包"未正确加载 [英] The 'Provider Package' did not load correctly
问题描述
VS 2013 Professional - 版本 12.0.31101.00 更新 4
突然间，每当我尝试打开一个项目(MVC 项目或 Python 项目)时，我得到:
All of a sudden, whenever I try to open a project (MVC project or Python project), I get:
ProviderPackage"包未正确加载.
The 'ProviderPackage' package did not load correctly.
问题可能是由配置更改或安装引起的的另一个扩展.您可以通过检查获得更多信息文件'C:\Users\xxxx\AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml'.
The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\xxxx\AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml'.
在我的 AppData\Roaming 中，没有 12.0 文件夹！在 AppData\Local 中，有一个 12.0 文件夹，但没有 ActivityLog.xml 文件.
In my AppData\Roaming, there is no 12.0 folder! In AppData\Local, there is a 12.0 folder but there is no ActivityLog.xml file.
当我忽略该消息并按 F5 运行时，经过大量磁盘移动后，Visual Studio 只是关闭并消失了.
When I ignore the message and press F5 to run, after lots of disk movement, Visual Studio simply closes and disappears.
我已经修复了几次，完全相同的行为仍然存在.
I have repaired a few times and the exact same behavior persists.
当我尝试运行 devenv.exe/setup 或 devenv.exe/resetuserdata 时，完全没有任何反应.没有错误，没有启动任何进程，什么也没有.不带任何参数运行 devenv.exe 会启动 VS.
When I try to run devenv.exe /setup or devenv.exe /resetuserdata, absolutely nothing happens. No error, no process is launched, nothing. Running devenv.exe without any parameters does launch VS.
有什么问题?如果有其他解决方案，我会犹豫卸载并重新安装.
What can be wrong? I hesitate to uninstall and reinstall if there is some other solution.
1 天后:卸载 VS 2013 并重新安装，然后应用更新 4.
1 day later: Uninstalled VS 2013 and reinstalled, and then applied Update 4.
MVC 项目的问题仍然相同:ProviderPackage 没有正确加载，并且在运行项目时 VS 关闭并消失.
Problem is still the same for the MVC project: ProviderPackage did not load correctly, and when running project VS closes and disappears.
ActivityLog.xml 中的最后一条记录说:
Last record in ActivityLog.xml says:
<entry>
<record>1120</record>
<time>2015/03/17 06:38:43.882</time>
<type>Error</type>
