title: The type or namespace name 'DbEntityEntry<TEntity>' could not be found
body: <p>I have the following interface that I used before EF7. When I try to build the application using EF7, I receive the following error, and I cannot seem to find this type anywhere. I'd really appreciate your suggestions about how to change this code for EF7.  </p>
