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?

最快的方法是更改Build配置类型并再次返回到以前的配置。
其他回答
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
必须在关闭后终止进程。 我用;
Process.GetCurrentProcess().Kill();
将此代码添加到您用于关闭的关闭事件或方法。
在Visual Studio 2010中，我也会定期遇到这个问题。关闭Visual Studio，删除bin和obj目录，并重新启动将修复一个构建。然后问题又回来了。我已经尝试了这个帖子上的所有其他答案，但没有一个对我有效。对我来说，唯一能永久解决这个问题的方法就是打开项目设置，关闭“启用Visual Studio托管进程”，构建，再打开，然后再次构建。
进入“工具>>选项>>数据库工具>>常规” 检查脚本/查询执行情况
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.
