When NOT to use the Entity Framework

I have been playing around with the EF to see what it can handle. Also many articles and posts explain the various scenarios in which the EF can be used, however if miss the "con" side somehow. Now my question is, in what kind of scenarios should I stay away from the Entity Framework ?

If you have some experience in this field, tell me what scenarios don't play well with the EF. Tell me about some downsides you experienced where you whished you would have chosen a different technology.

Not all data models map nicely to application Entities. If the mapping isn't relatively straightforward, I'd skip the Entity Framework. You'll find yourself doing handstands to make it work without any clear benefit.

Anders Hejlsberg had some interesting comments about object/relational mapping here.
