Graphify C#

Compiler-accurate Find Usages for coding agents

🧑‍💻 Coding & Dev ToolsOpen SourceY▲ 46 on HNLaunched September 27, 2026

graphify-csharp is a free, headless Roslyn/MSBuild indexer that gives coding agents compiler-accurate Find Usages for C#. It turns a solution into deterministic semantic evidence: exact callers, references, implementations, inheritance, overrides and argument bindings, even across overloads, generics and project boundaries. First shared by its maker on Show HN: https://news.ycombinator.com/item?id=49667188

Overview

Who is it for?

C# developers using coding agents like Codex, Claude Code and Cursor.

Problem

Agents rely on text search, which can't tell which overload a call binds to or which implementation an interface call dispatches to.

Solution

Ask the compiler through Roslyn and MSBuild for exact symbol relationships and hand them to the agent.

What makes it unique

The semantic-navigation part of Rider or ReSharper, exported for agents with no IDE, database or prebuilt DLLs.

Graphify C# FAQ

Which agents does it work with?

Codex, Claude Code, Cursor and other tools that need to reason about a C# codebase.

How is it distributed?

As a NuGet package, MIT licensed.

Do I need an IDE?

No. It runs headless.
