Graphify C# - Compiler-accurate Find Usages for coding agents
Show HN: Graphify C# – Compiler-accurate Find Usages for coding agents
Graphify C# is a free, headless Roslyn/MSBuild indexer that gives coding agents compiler-accurate Find Usages for C#. It turns source code into deterministic semantic evidence—resolved callers, references, implementations, inheritance, and overrides—even across overloads, generics, and projects. Install it as a .NET tool, index your solution to JSON, and let agents like Codex or Claude Code answer questions about exact overloads, interface implementations, and test-only usages. No IDE, no compiled DLLs, no database required.
Stop making your agent guess. Graphify C# loads the project through MSBuild and asks Roslyn what every symbol actually means, emitting stable identities and directed relationships that an agent can inspect instead of infer.

Love to see C# love.
It's a great language. Super underrated in my opinion.
Unions coming in .NET 11 / C# 15 are going to be great.

Hey man, just wanted to say thanks! I pulled this down and adapted the skill for Unity development, keeping Graphify C# as an external analysis tool. My adapted skill isn’t publicly available yet, and I'm going to add it into my standard Unity Package development workflow to see if I can find some additional value in how the CLI and structured JSON make semantic information accessible to coding agents. I think this will help (maybe not on a full Unity game) but if you'r building multiple Unity Packages or have existing Unity Packages. Appreciate you sharing this!

Is this compatible with Graphify-Labs/graphify, w/r/t existing output formats?
