Hi, is there a list of programming features that are not supported from C# .Net Core 3.1 onwards? For example Microsoft.Data.SqlClient is recommended in comparison with System.Data.SqlClient. Is there such a comprehensive list as one-stop-shop from Microsoft documentation or otherwise?

thanks for your help.

    I normally consult the migration guides when upgrading .NET Core version:
    https://learn.microsoft.com/en-us/aspnet/core/migration/30-to-31?view=aspnetcore-5.0&tabs=visual-studio

    If you look in the navigation bar there are guides to migrate between all major versions. They list most of the major deprecations/moved libraries/configuration & code changes and it's quite comprehensive.
