roslyn: VS2019 intellisense completes with bad quality results

Version Used: Visual Studio 2019

Maybe my mind is playing tricks on me, but since I updated to VS 2019 I feel like I’m fighting a lot against Intellisense.

Specifically: I would very quickly type the beginning of what I’m intending to write, hit complete (tab, space, enter – depends on the situation)… and not get the expected (best) result. So I have to backspace, start again (slowly), get the “right” completion and move on.

This was not the case in VS2017, I could write code quickly, completing everything along the way.

Because writing code is the “core loop” of coder, having to stop and backspace because of bad Intellisense is very irksome and a major frustration after my upgrade.

I may be completely off, but I have a suspicion / theory about what has changed:

My guess is that new Intellisense is completely async and I am getting its best suggestion at the time I hit “complete”. So when typing int<tab> I think I might get the completion for in if Intellisense has not finished filtering and sorting the int prefix.

I love the improved “snapiness” of VS 2019, but if I’m correct about Intellisense it should wait for the full suggestions to complete before completing text in editor.
