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?

I experienced the error-messages when attempting to build the primary WinForms (XAF) project. I could only execute the application one time then needed to shutdown the VS2015 IDE and restart before a rebuild could be performed. After some digging in the project's property pages - in the "debug" property page, a check box was selected - Enable the Visual Studio Hosting Process. I unchecked and restarted the IDE, the application is now building without - "unable to copy the {project}.exe" messages.
Visual Studio托管过程的目的是什么?

如果你使用Visual Studio Code (vsCode)遇到这个问题，或者你坚持使用终端命令，clean命令将删除构建文件，并通常修复描述的问题:
dotnet clean
然后，您可以返回运行:
dotnet build
or
dotnet run
将此添加到预构建:
(if exist "$(TargetDir)*old.exe" del "$(TargetDir)*old.exe") & (if exist "$(TargetDir)*.exe" ren "$(TargetDir)*.exe" *.old.exe)
用款。我通过编辑MSBuild.Community.Tasks.Targets文件并更改bin路径解决了这个问题:
<MSBuildDnnBinPath Condition="'$(MSBuildDnnBinPath)' == ''">$(MSBuildProjectDirectory)\bin</MSBuildDnnBinPath>
对我来说，这是一个许可问题。我必须以管理员的身份运行Visual Studio。
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)"
