Im using VS 2019, I see many video tutorials where visual studio would show a red circle mark on the opened script tabs if there were error in the codes. Where can I find the setting for it?
Try if this works:
Go to Edit → Preferences → External Tools
Change “External Script Editor” to Visual Studio 2019.
@Vivien_Lynn if I had a non-compile error I would only see it in Unity Editor but VS woudld not show a red dot on the tab to let me know which script has an syntax error.
@jangyejun just checked my perferences my external script editor is already set to VS 2019.
