I did not! Rider is extremely satisfying to use.

Is devkit better than Rider ?

I tried to use vscode c# devkit but it is horribly unstable and has severe bugs that make it unusable for my projects. But I'm really happy with vscode + omnisharp. I never used rider so I cannot really say which is better but I tend to not like jetbrains IDEs (from experience with IntelliJ and webstorm).
