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?

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)
其他回答
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).
我通过在任务管理器中杀死IISExpress解决了这个问题
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.
我发疯了，试图找到为什么系统进程在我正在工作的EXE上保持一个打开的句柄，在它被终止后的另一分钟，我得到了与OP相同的错误。
原因是之前的开发人员在使用(){}时没有包装IDisposable对象。一旦IDisposable对象正确地销毁自己，错误不再发生，我能够立即重建。
如果您正在调试T4模板，那么这种情况经常发生。我的解决方案(在MS修复这个问题之前)将只是杀死这个进程:
任务管理器—> User—> T4VSHostProcess.exe
此过程仅在调试T4模板时出现，而不会在运行T4模板时出现。
