Rolling Into .NET 11: Modeling a Board Game with C# 15

Tue, 13 Oct 2026 09:00:00 +0000

This post is part 1 of a 6-part series on domain modeling with C# 15 and .NET 11, told through a small board game.

It’s your turn. You can roll the dice, play a card, or pass. You pick one, and the game moves on.

Now, how does your code know which one happened?

That sounds like a simple question. In most C# codebases, the answer is “it depends on which property is set,” or “check the string,” or “cast it and hope.” All three work - right up until someone adds a new kind of turn, mistypes a string, or sets two properties at once. Then the compiler shrugs, the build stays green, and the bug shows up at runtime.
