在VS2012 c#项目的构建过程中，我一直得到这个错误
Error 41 Could not copy "obj\Debug\WeinGartner.WeinCad.exe" to
"bin\Debug\WeinGartner.WeinCad.exe".
Exceeded retry count of 10. Failed.
Error 42 Unable to copy file "obj\Debug\WeinGartner.WeinCad.exe" to
"bin\Debug\WeinGartner.WeinCad.exe". The process cannot access the file
'bin\Debug\WeinGartner.WeinCad.exe' because it is being used by another
process.
现在我知道该终止进程了
Weingartner.WeinCad.vhost.exe
(有时)有用，但这让我很紧张。有办法阻止这一切发生吗?

I ran into this as well. It turns out that I had been testing with a service which I had built myself and which was running out the of the ..\bin\release directory of one of the projects in my solution. I had got the service running, but I forget to stop/uninstall it before returning to testing. As a result, it was holding on to one of the dlls that I reference and which needed to be moved (automatically as a dependency) from one project's bin/release subfolders to another. Stopping the service solved the problem.

我也遇到过同样的问题，我尝试了这里提到的很多不同的方法，但没有一个对我有效，唯一对我有效的解决方案是:
从解决方案的DEBUG文件夹中删除READ ONLY属性 将此添加到构建事件:如果存在“$(TargetPath)”。$(TargetPath).locked" $(TargetPath)。锁定" if exists "$(TargetPath)" move "$(TargetPath)"“$(定位路径).locked”
我在Visual Studio 2013中遇到过类似的错误消息。
大多数情况下，我发现这种情况发生在调试进程因为异常而停止时。
当clean+build不能为我解决这个问题时，我通过以下方法取得了成功:
关闭Visual Studio 删除bin和obj文件夹 重新开放Visual Studio。
此“bug”自Visual Studio 2003以来一直存在。
最后，我还发现我通常可以通过简单地重命名可执行文件然后删除它来克服这个问题。
我意识到这只是为这个问题增加了一个已经非常多的答案，但我认为值得一提的是，尽管不完美，但@Stefano， @MichaelRibbons和@IvanFerrerVilla给出的答案的组合已经提供了一些不错的成功，因为他们各自都不太成功。

一个解决方法是把它放在>项目的预构建事件命令行属性中(在构建事件选项卡中):
代码片段
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
在任务管理器中检查任何运行.exe .exe的进程
