Detect C# in any GitHub repo

C# is one of the language technologies Stack Fingerprint recognises automatically when it scans a public repository.

How C# is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags C# when it finds any of these:

  • File extensions: .cs

C# README badge

A static badge you can paste anywhere in Markdown:

C# badge

Markdown
![C#](https://img.shields.io/badge/C%23-512BD4?style=for-the-badge&logo=csharp&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so C# (and everything around it) appears or disappears on its own:

README.md
[![Stack Fingerprint](https://stackfingerprint.vercel.app/api/card?repo=OWNER/REPO)](https://stackfingerprint.vercel.app/?repo=OWNER/REPO)

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
