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
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
删除Bin文件夹中的Debug或Release文件夹下的所有.cache文件。
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)"
这是因为你已经关闭了你的应用程序，但它仍然在后台运行。
临时解决方案:
进入任务管理器(Ctrl + Shift + Esc)。 进入进程选项卡，找到“YourProjectName.exe”。 如果找不到自己的进程，请勾选“显示来自所有用户的进程”。 结束处理
永久解决方案:必须通过编码关闭应用程序。这是代码…
System.Windows.Forms.Application.Exit();
您必须以所有形式将此代码放入表单的关闭事件中。例子:
private void frm_menu_FormClosing(object sender, FormClosingEventArgs e)
{
System.Windows.Forms.Application.Exit();
}
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).
在你的主项目taskkill /f /fi "pid gt 0" /im "YourProcess.vshost.exe"中添加预构建事件
