在开发过程中，经常需要调试运行中的程序。对于Visual Studio用户来说，通常的做法是使用“附加到进程”功能。然而，这个过程可能会变得繁琐，尤其是当应用程序名称以英文字母表后半部分的常见字母开头时，或者当长时间工作在一个项目上，选择错误的进程变得容易。
为了简化这个过程，可以编写一个宏，这个宏会自动找到启动项目的输出文件路径，并附加到对应的进程。这样，就不需要手动在进程列表中搜索并选择应用程序了。
JustAttach 宏是一个Visual Studio宏，它会自动附加到解决方案的启动项目的输出文件路径对应的进程。以下是如何使用这个宏的步骤：
现在，每当需要附加到进程时，只需按下设置的快捷键，宏就会自动执行。
以下是JustAttach宏的完整代码。这个宏首先找到启动项目的输出文件路径，然后附加到对应的进程。
