It's because Tab accepts copilot suggestion, you have to press Enter instead to accept the language server suggestion.
Alright, he's just holding it wrong.
Why can't all the suggestions come through the same UI element? That's beyond my understanding.
You'd get suggestions from,
- multiple language servers
- matches from the same buffer/project or sibling pane (tab,window, whatever you call it)
- matches from the dictionary
Yes, and what a mess it has been.
Intellisense + Intellicode + Roslynator (extension) combined were really the height of productivity in Visual Studio. Now they've driven a steam-roller over all of that, forced CoPilot down our throats.
I LIKE CoPilot's "chat" interface, and agents are fine too (although Claude in VS Code is tons better), but CoPilot auto-complete is negative value and shouldn't be used.
