Show HN: Graphify C# – Compiler-accurate Find Usages for coding agents

Graphify C# is a free, compiler-accurate indexing tool that extracts semantic information from C# codebases using Roslyn and MSBuild, enabling coding agents to perform reliable "Find Usages" queries by resolving exact method calls, implementations, and type relationships instead of relying on text matching. Unlike traditional text-based searches, it provides deterministic, queryable semantic evidence across overloads, generics, and projects without requiring an IDE or compiled DLLs. The tool is MIT-licensed and designed specifically for AI coding agents like Claude Code and Codex.
