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?

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)"

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.
我终于怎么修了。为什么我们不能在第一次调试后继续调试，因为第一次调试exe仍在运行。这样，在第一次调试之后，您需要进入任务管理器->进程选项卡->[您的项目名称exe]结束exe进程。
这对我很有用:)
我也遇到过同样的问题，我尝试了这里提到的很多不同的方法，但没有一个对我有效，唯一对我有效的解决方案是:
从解决方案的DEBUG文件夹中删除READ ONLY属性 将此添加到构建事件:如果存在“$(TargetPath)”。$(TargetPath).locked" $(TargetPath)。锁定" if exists "$(TargetPath)" move "$(TargetPath)"“$(定位路径).locked”
看看另一个答案。基本上，你可以让MSBuild.exe进程在后台运行，消耗资源文件。如果你有任何构建前或构建后的任务，导致MSBuild通过命令行启动，尝试添加"/nr:false"标志到这个命令。但是，关于更具体的细节，请参见前面的回答。
我想我解决了这个问题，当一个进程在调试选项中中断时，我删除了中断所有进程的复选标记(op的第一个截图->第二个选项)。 自从我未检查它以来，它已经运行了一段时间。 我在我的项目中使用MySql NET连接器和DevExpress控件。可能其中一个没有很好地处理连接、绑定等，因为这个标志被激活了。
编辑:绝对有效!没有更多的“无法复制文件”，没有更多的表单设计器错误。
