I built SharpFocus, a static analysis extension for C# that brings program slicing to VS Code. It's heavily inspired by Flowistry for Rust.
Click any variable, and it instantly highlights its complete data flow (what influenced it, and what it influences), fading out all irrelevant code. It's designed to make debugging and understanding complex methods faster. The analysis is powered by Roslyn.
It's open-source, and I'd appreciate any feedback.
