Is there an easy way of checking whether an entity type (not instance) has a PK with an identy sequence? From non-DAL code?

None in Adapter. In Selfservicing: ((IFieldPersistenceInfo)field).IsIdentity

OK, how about a hard way. : (I don't mind using reflection if I have to, I just don't know where to reflect to)

In adapter, the information isn't in the field, it's in the persistenceinfo object, which isn't available in the entity (only through the adapter). In selfservicing, this info is in the field, so it's available.

So if you're using adapter, you have to ask the adapter (using the getfieldpersistenceinfo methods, which are protected) the fieldpersistenceinfo object and then check the flag.
