A case study in implementing domain-specific types.
In real‑world programming, certain domains impose strict constraints on data.
For example, in biomedical informatics, many patient attributes must be non‑negative: a natural integer (≥ 0) or a natural float (≥ 0.0).
Most programming languages do not natively support domain‑specific types.
This case study demonstrates how to model such constraints explicitly in C#.
Ada integrates domain constraints directly into its type system.
Most languages lack this feature, but we can simulate type constraints in C# using smart constructors.
This prevents invalid data from leaking into the core logic and enforces domain rules at the boundary.
Here, we provide an C# implementation of a natural number type as a case study.
