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?

当前回答
我能够修复这个问题(VS 2010)通过提供以下预构建操作;
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
其他回答
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。
此问题通常在运行测试时发生。如果这是你的情况，只需转到任务管理器并杀死testHost
遵循以下步骤
打开任务管理器(Ctrl + Alt + Delete) 在Performance选项卡下选择<ProjectNameOfYours.exe>。 单击End Process。 现在构建解决方案。
以上步骤永久地解决了错误。
如果没有一个答案是正确的，试试这个简单的检查。 找到任何MSbuild.exe运行和持有您的项目EXE。杀死MSBuild.exe，你应该很好。
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)"

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)"
