So all of the sudden I am unable to add new entities / fields to my project. The code generates and compiles OK, but in VS 2012 I am unable use my new entities. I have access to them, and intellisense works, but my code will not compile if I try to reference them.
I just downloaded the latest build for version 3.5, although I do'nt think that has anything to do with the problem.. it has always worked just fine before. Is there perhaps a setting in the designer that I messed up?
The error doesn't really make sense because all of my other entities work just fine. Just the new ones I add. And then I don't get compilation issues unless I try to use them.
Here is the compilation error :

Same thing if I try to use linq:

Any idea what might be going on here ? Here are the LLBLGEN DLL's I am referencing:
