❔ Reason

The .NET ecosystem offers many powerful analyzers, including built-in ones like CAxxxx and IDExxxx, as well as well-known third-party analyzers based on the Roslyn API, such as Roslynator and StyleCop.

Despite their wide coverage, certain rules remain uncovered. 👨‍🍳 kuker analyzer is designed to address these gaps by providing additional, highly focused analysis rules.
