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?

似乎通过更改项目的程序集名称就可以解决这个问题。
所以不是这样
我把它变成这个
注意，我只是把它从Increment and Recall改成了Increment_Recall，我只是去掉了空格。它现在对我来说工作得很好。
其他回答
关闭进程w3wp.exe (IIS)通常可以解决这个问题。通常，您可以通过导航到bin文件夹并尝试删除它来了解对该文件具有锁的进程。如果另一个进程正在使用它，将弹出的错误消息将包含需要被杀死的进程的名称。
使用Blazor和Fluent UI Web组件，我在发布时得到了以下错误:

看着
C:\Users\oscar\source\repos\MyVeryLongProjectName12345678\MyVeryLongProjectName12345678\Server\obj\Release\net6.0\PubTmp\Out\wwwroot\_content\Microsoft.Fast.Components.FluentUI\icons\TextDirectionHorizontalRight\ko\text_direction_horizontal_right_24_regular.svg
长度为261个字符。
然后我尝试启用长路径并重新启动我的计算机。
https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry
这没有工作，我得到了同样的错误。然后，我将项目移动到C:\MyVeryLongProjectName12345678\，而不是C:\ users \奥斯卡\source\ rep\ MyVeryLongProjectName12345678\。这样做之后，一切都解决了。
您可以通过脚本终止应用程序。
如果你的应用程序名为myapp.exe，在终端中运行下一个脚本:
taskkill /IM myapp.exe /F
参数为:
/IM application name (imagename)
/F Specifies to forcefully terminate the process(es).
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)"
按Cntrl+alt+Delete，然后进入资源监视器，在CPU选项卡下选择您的exe名称，右键单击并杀死该进程。
在任务管理器中检查任何运行.exe .exe的进程
