The problem is that once you support an Enum value you can't remove it anymore, at least not if you don't want to break older versions of an application.

If so, that must be a very common problem (keeping static and dynamic version in sync) but I guess it's really just not what Enums are for. However, it WOULD be a very sweet thing to be able to infer the enums from i.e. a db table. But for this I guess you need a radical dynamic change to the Enum concept, a data provider API, type inference and IDE support - a kin to what you can do in LINQ.

There's no way to support that with Enums, or rather, a list of enumerated values cannot change between versions a the same data dictionary.
