exercism-csharp

Solutions to C# exercises from Exercism — a free platform for practicing programming languages through small, focused exercises with mentor feedback.

About

This repo tracks my progress through the Exercism C# track, sort of. Each exercise lives in its own project under src/, with a matching test project under test/, following the typical src/test structure.

I'm not working through the track in order — I pick exercises based on what looks interesting rather than following the suggested sequence. Later on, the repo also became a sandbox for Claude Code experiments, testing how different models behave under different circumstances against small, self-contained, well-tested problems.
