I installed DarkTheme2019. When I switch to it, it changes my VS2019 theme to "Blue". In VS2019, I switch back to "Dark" and then in VS2022 it goes from "Dark(2019)" to "Dark".
VS2022 at least kept the font change from "Dark(2019).
Is there a way to have the two Visual Studio's not be affected by what the other does?
It's a known issue: https://developercommunity.visualstudio.com/t/visual-studio-2022-setting-the-theme-in-2022-chang/1466144
It's not fixed yet (in Visual Studio 2022 version 17.1.0) regardless of what that page says.
