当我打开Visual Studio 2013并加载我的解决方案时,我收到一条错误消息,告诉我测试窗口"无法加载,我对此表示欢迎.
When I open Visual Studio 2013 and load my solution I'm greeted by an error message telling me the Test Window is unable to load.
The composition produced a single composition error. The root cause is provided below.

Visual Studio is unable to run tests at all. Closing an re-opening the test window shows the same error.
推荐答案这似乎是由组件模型缓存中的损坏引起的.
This seems to be caused by a corruption in the Component Model Cache.
关闭Visual Studio的所有实例,然后导航到文件夹并将其删除.
Close all instances of Visual Studio, then navigate to folder and delete it.
%LOCALAPPDATA%\ Microsoft \ VisualStudio \ 12.0 \ ComponentModelCache
%LOCALAPPDATA%\Microsoft\VisualStudio\12.0\ComponentModelCache
现在重新启动Visual Studio,它应该可以再次工作.
Now restart Visual Studio and it should work again.
