About this course
The journey
Katas are short exercises you repeat until the solution flows. Kata Depot has two hundred of them, each with an xUnit test suite that tells you when you are done and a model solution written in modern C#.
Choose your fare from €1 to €100. Each stop on the fare ladder unlocks the next set of forty katas — €1 gets the first set, €100 gets all five.
