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 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.

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:

然后我尝试启用长路径并重新启动我的计算机。

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。

我注意到一些答案可以解决我的问题,但是,以防有人有和我一样的问题。

如果你正在运行一个控制台应用程序:在你做任何其他事情之前。

确保您已经关闭了从以前的版本中打开的任何控制台窗口。例如,我只是在一个控制台应用程序中测试一些代码,我没有意识到以前运行程序时的控制台窗口是打开的。在我调试的过程中,窗口被推到后面,我看不到它。只是说,这可能是你的问题,所以检查确保这不是问题。

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)"

REM References:

脚本需要从每个VS项目预构建事件中调用。

我正在研究一个微服务项目解决方案,我需要同时运行两个项目,冲突发生在lunchsettings.json applicationurl: {portNo}部分用于两个正在运行的项目是相同的端口

lunchsettings。第一个项目的Json

...
"Project#1": {
  ...
  "applicationUrl": "http://localhost:5001",
  ...
}

lunchsettings。第二个项目的Json

...
"Project#2": {
  ...
  "applicationUrl": "http://localhost:5001",
  ...
}

来修复它

lunchsettings。第一个项目的Json

...
"Project#1": {
  ...
  "applicationUrl": "http://localhost:5001",
  ...
}

lunchsettings。Json for secondproject

...
"Project#2": {
  ...
