EFv4 CTP5 some missing features (mapping)
Entity Framework v4 CTP5 added some new nice features since CTP4, for example the DbSet<T>.Local property I was blogging about or Validation. But, sadly, there’s something missing, mainly due to huge refactoring.
I hit the wall with one in particular. It’s entity splitting together with TPH inheritance. If you try to map it, you’ll get Entity splitting cannot be specified for type '<entity type>' since it is part of an inheritance hierarchy.. Bummer. So one of the projects I’m working on now, is stuck in CTP4. 
On the other hand, the good news (from reliable source 
) is, that in RTM this will be working fine.

Are you sure that it’s not possible? Do you have a source for this? I’ve found the “new” CTP5 solution to most of my other CTP4 mappings, and would like to know for sure if this is really not supported under ctp5.
Thanks

Yes, I’m sure. I was talking about it with guys from EF team (I think this is reliable source
).
