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.
