I don't get it. Even in a statically typed language like C# you can change the domain model and your application will still compile as if nothing happened. In this post we will address this and see how F# can help with such pitfalls of C# enumerations.

The problem with enumerations is simply that when we add new cases especially in a large code base, it can be really hard to find and update all dependent source code which might lead to errors at runtime.
The compiler will not help to find all the places that have to be updated. A text-based search isn't reliable.
Here is how things can go wrong.
