Analyzing Code Quality with LINQ and NDepend

I’ve been building an open-source personal project (C# REPL) and spending a good chunk of time on code quality. I self-impose a zero-warning policy, use nullable reference types, track unit test coverage, etc.

After ensuring all the Visual Studio / Roslyn code analyzer warnings were fixed, I thought I’d try out NDepend to get a second opinion, and also understand its capabilities. After downloading a free trial of NDepend and spending some time with it, I was pretty impressed with its technical underpinnings as they’re exposed to the end user. Spoilers: It’s LINQ all the way down.

Solving the Zebra Puzzle with LINQ and C# 7

I recently ran across the Zebra Puzzle, a logic puzzle from about 50 years ago:

  1. There are five houses.
  2. The Englishman lives in the red house.
  3. The Spaniard owns the dog.
  4. Coffee is drunk in the green house.
  5. The Ukrainian drinks tea.
  6. The green house is immediately to the right of the ivory house.
  7. The Old Gold smoker owns snails.
  8. Kools are smoked in the yellow house.
  9. Milk is drunk in the middle house.
  10. The Norwegian lives in the first house.
  11. The man who smokes Chesterfields lives in the house next to the man with the fox.
  12. Kools are smoked in the house next to the house where the horse is kept.
  13. The Lucky Strike smoker drinks orange juice.
  14. The Japanese smokes Parliaments.
  15. The Norwegian lives next to the blue house.

Now, continue.
