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
我没有意识到我仍然连接着调试器，并试图在同一个Visual Studio实例中构建。一旦我停止调试器，我就能够构建。

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"
异常
在某些情况下，在Visual Studio当你(Build || Rebuild)在上面 运行IISExpress时，你会遇到这个异常:
无法复制文件"obj\Debug\YourProjectName.dll"到bin\YourProjectName.dll"。进程无法访问该文件 'bin\YourProjectName.dll'，因为它正在被其他人使用 过程
解决方案
右键单击需要构建的web项目。 单击属性。 在左侧选择Build Events选项卡。 在Pre-build events命令行中粘贴这两行:
tasklist /fi “imagename eq iisexpress.exe” |find “：” > NUL 如果错误级别 1 任务杀死 /f /im “iisexpress.exe”
你很好!

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
