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?
调试器设置为
当前回答
删除Bin文件夹中的Debug或Release文件夹下的所有.cache文件。
其他回答
在你的主项目taskkill /f /fi "pid gt 0" /im "YourProcess.vshost.exe"中添加预构建事件
问题是调试器/构建器创建的可执行文件或库被反病毒程序识别为威胁，因此在可以执行之前立即删除。
最好你应该调整你的反病毒软件，不分析你的项目文件夹。
按照从好到坏的顺序，有以下几种方法:
将项目文件夹从防病毒程序中排除 不包括pdb文件(不是100%保证修复) 关闭实时保护(不推荐)
将此添加到预构建:
(if exist "$(TargetDir)*old.exe" del "$(TargetDir)*old.exe") & (if exist "$(TargetDir)*.exe" ren "$(TargetDir)*.exe" *.old.exe)
看看另一个答案。基本上，你可以让MSBuild.exe进程在后台运行，消耗资源文件。如果你有任何构建前或构建后的任务，导致MSBuild通过命令行启动，尝试添加"/nr:false"标志到这个命令。但是，关于更具体的细节，请参见前面的回答。
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.
