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?
调试器设置为
当前回答
在我的情况下(Windows 10, Visual Studio 2015):
任务管理器->用户-> EndTask=>vshost.exe
(它会立即重新启动，你可以重新构建)
其他回答
花了几个小时试图解决这个问题，然后发现我正在处理一个服务-记住停止任何服务作为解决方案的一部分!
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

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。
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。
在我的例子中，我在发布到它无法访问的文件夹时遇到了麻烦。您可以通过尝试发布到您的c驱动器中的一个文件夹来排除这种情况，您应该不会有访问问题。
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)"

脚本需要从每个VS项目预构建事件中调用。
