Is your feature request related to a problem? Please describe. Outdated documentation

Describe the solution you'd like Is it possible to update the docs for .net core section of the website? It looks like they haven't been touched in 4 years and references netcoreapp2.0. Ideally I'd like to see working examples for each provider for .net 6. I've poured over a whole slew of github comments on trying to get a basic example to build with mssql without any luck.

Describe alternatives you've considered No real alternative, documentation should be up-to-date.
