【问题描述】：
我想在 Visual Studio 2019（版本：16.9.5）中发布我的 WPF 应用程序。
我在解决方案资源管理器中右键单击该项目，单击Publish 并打开一个新选项卡。该选项卡应显示发布设置，但会无休止地加载。
我尝试使用空白/新控制台应用程序，但我遇到了同样的问题。

【问题讨论】：
-
您是否尝试使用安装程序清除缓存或修复 VS？
-
这个问题发生在VS19 v16.9.4，所以我刚刚更新到16.9.5，但同样的问题。我也删除了缓存，但还是一样
-
您尝试修复了吗？
-
是的，我试过了。没有影响
-
你试过检查 VS 日志吗？是否启用了任何扩展？我还读到 AntiVirus 可能会导致 VS 挂起。虽然我没有经历过，但不确定。
