The Model in each version is perfect which was driving me crazy.

Not saying this is the answer to the OP's question but it is definately another reason for this error.

I was facing the same issue, when I added one column to db and added respective property to entity(edmx). I was also using source control for my solution. As I noticed, while saving changes to any file, save action prompts with overwrite option. So, I overwritten the designer.cs as well config file and problem gets resolved.
