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?

在我的例子中，VS不能复制的文件是. task项目的文件，所以问题是我有一些本地运行的计划任务。一旦我停止并禁用它们，复制问题就消失了。

对我来说，它是Avast反病毒，不让visual studio写入/读取/执行文件。所以我不得不将Visual studio 2010/2012文件夹添加到防病毒排除列表中。就在那之后……它的工作原理。
如果我使用VS2012在WP8上编辑Xaml页面，每次部署都会遇到这个问题。
我需要要么不打开Xaml页面，要么使用进程资源管理器杀死进程XDesProc.exe。
如果您得到这个错误，那么我建议使用进程资源管理器来查看发生了什么(即使这是一个不同的问题)。只要找到进程“WeinGartner.WeinCad.exe”，它应该显示进程和处理访问文件(好吧，至少当杀死vhost文件不解决问题)。
在任务管理器中检查任何运行.exe .exe的进程
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。
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.
