visual-studio - 无法将 "obj\Debug\{project}.dll"复制到 "bin\{project}.dll"

Question

最近，当我尝试运行我的项目时，Visual Studio Express 2013 for web 经常抛出此错误，我发现的唯一解决方法是退出并重新启动 Visual Studio 或(有时)完全重新启动 Windows。什么会导致这样的事情？

通过转到项目属性(右键单击解决方案资源管理器中的项目，然后选择“属性”选项)，选择“构建事件”选项卡，在项目中创建预构建操作。添加此代码:

if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if not exist "$(TargetPath).locked" move "$(TargetPath)" "$(TargetPath).locked"
