当我在Visual Studio 2019中将项目发布到GitHub时，为什么progressBar会继续运行？

如“通过推共享代码”所示，同步将推和拉。

problem/187028 提到：

The reason the UI is blocked when you do a "Sync" (which is a push and a pull) is that files may be changed on disk. Allowing you to change files while a pull is in progress may lead to lost changes and could lead to unexpected results.

So if you do a Sync, and then are able to work/modify any file, you are sure that everything was pushed/pulled.

The progress bar issue is supposed to be fixed in recent version of Visual Studio, but problem/159277 included the workaround:

open the identity picker and select "Add an account".
You will then be prompted to choose an identity, and you can choose the one that is currently selected.
The pane should then refresh to show the VSTS account and repo fields.

推操作似乎在后台运行–

是：这意味着您可以在推送处理期间继续使用Visual Studio。
但是，如果您关闭Visual Studio，则该git push命令将被中断，并且不会完成。
