I have a C# library that's used by several executables.  There's only a couple namespaces in the library, and I just noticed that one of the namespaces has quite a few classes in it.  I've always avoided having too many classes in a single namespace because of categorization, and because subconsciously, I think it looks prettier to have a deeper hierarchy of namespaces.My question is:  does anyone else consider it a code smell when a namespace has many classes - even if the classes relate to each other?  Would you put in a lot of effort to find nuances in the classes that allows for subcategorization?
Number of Classes in a Namespace - Code Smell?
c#;count;namespace
Not necessarily. If all the classes indeed belong to the category defined by the namespace, it's fine then.What you can do is to look at the classes and reflect on the possibility of merging some of them. Could well be small groups of those classes support family functionality but were implemented separately for some historic reasons. Now when sufficient time has elapsed, a better composition might be possible.
