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?

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)。

下面是一个脚本，绝对可以摆脱这个问题:
REM This script is invoked before compiling an assembly, and if the target file exist, it moves it to a temporary location
REM The file-move works even if the existing assembly file is currently locked-by/in-use-in any process.
REM This way we can be sure that the compilation won't end up claiming the assembly cannot be erased!
echo PreBuildEvents
echo $(TargetPath) is %1
echo $(TargetFileName) is %2
echo $(TargetDir) is %3
echo $(TargetName) is %4
set dir=C:\temp\LockedAssemblies
if not exist %dir% (mkdir %dir%)
REM delete all assemblies moved not really locked by a process
del "%dir%\*" /q
REM assembly file (.exe / .dll) - .pdb file and eventually .xml file (documentation) are concerned
REM use %random% to let coexists several process that hold several versions of locked assemblies
if exist "%1" move "%1" "%dir%\%2.locked.%random%"
if exist "%3%4.pdb" move "%3%4.pdb" "%dir%\%4.pdb.locked%random%"
if exist "%3%4.xml.locked" del "%dir%\%4.xml.locked%random%"
REM Code with Macros
REM if exist "$(TargetPath)" move "$(TargetPath)" "C:\temp\LockedAssemblies\$(TargetFileName).locked.%random%"
REM if exist "$(TargetDir)$(TargetName).pdb" move "C:\temp\LockedAssemblies\$(TargetName).pdb" "$(TargetDir)$(TargetName).pdb.locked%random%"
REM if exist "$(TargetDir)$(TargetName).xml.locked" del "C:\temp\LockedAssemblies\$(TargetName).xml.locked%random%"
REM PreBuildEvent code
REM $(SolutionDir)\BuildProcess\PreBuildEvents.bat "$(TargetPath)" "$(TargetFileName)" "$(TargetDir)" "$(TargetName)"
REM References:

脚本需要从每个VS项目预构建事件中调用。
$(SolutionDir)\BuildProcess\PreBuildEvents.bat "$(TargetPath)" "$(TargetFileName)" "$(TargetDir)" "$(TargetName)"
我在Visual Studio 2013中遇到过类似的错误消息。
大多数情况下，我发现这种情况发生在调试进程因为异常而停止时。
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:
关闭Visual Studio 删除bin和obj文件夹 重新开放Visual Studio。
此“bug”自Visual Studio 2003以来一直存在。
最后，我还发现我通常可以通过简单地重命名可执行文件然后删除它来克服这个问题。
这个问题是查找以下错误时的第一个结果:
无法复制文件“…”，因为没有找到该文件。
在Visual Studio 2013(更新3)中构建时。
解决方案:卸载Visual Studio 2013中的“生产力工具”。

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.
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。
