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
我没有意识到我仍然连接着调试器，并试图在同一个Visual Studio实例中构建。一旦我停止调试器，我就能够构建。
其他回答
在我的案例中，Visual Studio 2105远程调试器是问题所在。当我在任务管理器中杀死这个任务时，我能够成功地在Visual Studio中重建我的应用程序。
我终于怎么修了。为什么我们不能在第一次调试后继续调试，因为第一次调试exe仍在运行。这样，在第一次调试之后，您需要进入任务管理器->进程选项卡->[您的项目名称exe]结束exe进程。
这对我很有用:)
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
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.
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>
