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?

对我来说，杀死vste .executionengine.exe进程(es)在90%的情况下解决了这个问题。如果这不起作用，那么也杀死QTAgent32.exe，然后删除项目的/bin和/obj文件夹。
这是我工作中最烦人的部分。：）
其他回答
我能够修复这个问题(VS 2010)通过提供以下预构建操作;
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
在我的情况下(Windows 10, Visual Studio 2015):
任务管理器->用户-> EndTask=>vshost.exe
(它会立即重新启动，你可以重新构建)
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.
在你的主项目taskkill /f /fi "pid gt 0" /im "YourProcess.vshost.exe"中添加预构建事件
我不能给出一个解决方案来防止这种情况发生，但你至少可以重命名锁定文件(windows资源管理器，或经典命令窗口)，然后编译/构建。不需要重启VS201x。如果有一些经验，你可以添加一个预构建脚本来删除旧文件或重命名，以防出现锁。
