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?

您可以通过脚本终止应用程序。
如果你的应用程序名为myapp.exe，在终端中运行下一个脚本:
taskkill /IM myapp.exe /F
参数为:
/IM application name (imagename)
/F Specifies to forcefully terminate the process(es).
其他回答
@Gerard的答案是正确的。
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:
Closing Visual Studio
Deleting the bin and obj folders, and
Reopening Visual Studio.
但我需要在主机上做一些额外的工作:
> Add-Migration Initial
> Update-Database
然后我开始调试，它起作用了。
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.
这发生在我使用IL支持插件时。
当您的项目中没有任何IL文件时(例如，因为您删除了最后一个文件)，构建将失败，如问题中所述。
删除对IL的支持解决了这个问题
如果你使用Visual Studio Code (vsCode)遇到这个问题，或者你坚持使用终端命令，clean命令将删除构建文件，并通常修复描述的问题:
dotnet clean
然后，您可以返回运行:
dotnet build
or
dotnet run
按Cntrl+alt+Delete，然后进入资源监视器，在CPU选项卡下选择您的exe名称，右键单击并杀死该进程。
