I\'ve looked, but it doesn\'t look like you can apply specific formatting to just comments.
As I have not found anything suitable so far, I use Vim. I set Open in &Vim as an external tool command, so I can just press Alt+T,V
to open the current file in it. In Vim, I find the comment (press /
for incremental search), select it (Shift+V
selects whole line) and gq
command formats the selected text. Finally, :wq
and I am back in Visual Studio.
Hopefully, some simple extension appears in future or VsVim will get this feature.
