The request names no specific product, and none of the candidates' sources show a dedicated .NET design-pattern tool, so the closest matches are the ones whose sources or indexed actions cover .NET or C# patterns: GitHub's indexed .NET design-pattern and best-practice reviews, Microsoft's .NET-specific P/Invoke pattern, and Sentry's .NET SDK. Note that the request is for patterns in general, so these are only partial fits.
A question back: Do you want a tool that reviews existing .NET code for design patterns, or one that teaches or scaffolds patterns for a new project?
