I usually run into issues at the boundaries in the system.

Usually moving from primitives into complex types does not account for serialization and deserialization between db and the client. This can be very annoying to work with in something like C#.

Usually it ends up resulting in alot more types and a lot more mapping between types.

However this has its own benefits, but is very boilerplate-y and is sluggish to work with when your domain changes.

Luckily, for C#, https://github.com/SteveDunn/Vogen now exists thanks to source code generators which soothes some of the issues.
