We have 8 EF models that combine to create our entity manager.  We added a 9th model and any entity from this model provides the following error during a query.  We tried adding a 10th model that has a completely different entity manager.  Same error.  Entity queries from the first 8 models work perfectly.
 
This error is killing us.  Any ideas??

Issue resolved. 

"We are pulling connection strings from our database and creating the EF connection strings dynamically in our KeyResolver.  However, we forgot that the model name changes even if the connection data stays the same, so DevForce was looking for entities in the assembly based on an incorrect model path."

Correct, issue resolved. Mistake on our end.
