EF4 POCO (not using T4): Mapping and metadata information could not be found for EntityType?

Ok, I guess i've got it. I reduced the second model (the one that brakes the project) to the following.

My guess is that ef is lookig at the wrong model. Is there any chance that the models are using the same namespace? You can modify the CSDLs namespace in the property window.

What happens if you modify the csdl namespace of the new, empty model?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
