Worked on enhancing the Orleans Analyzers within the dotnet/orleans repository, focusing on improving both accuracy and performance of code analysis. Leveraged C# and Roslyn Analyzers to implement fully qualified attribute matching, ensuring more precise detection and reducing false positives during analysis. Introduced per-compilation caching of attribute lookups, which decreased overhead and accelerated analysis across multiple compilations. Updated test syntax to align with .NET 8.0 standards and clarified code fixes by prefixing relevant attributes. These changes contributed to faster continuous integration feedback and increased confidence in code quality for Orleans-related updates, reflecting a thoughtful approach to code analysis tooling.
