Assumptions
-----------

* Using EF 6.1, MVC 5, VS 2013, C#
* I have an existing database model designed in Toad DM for SQL Server and it's very important keep it always updated

Steps and Notes
---------------

1. Using ADO.NET Entity Data Model I chose **Code First from Database** (**new feature in EF 6.1**) to generate the models. Note: Model classes and DbContext class generated successfuly but **NO .edmx or .tt file was generated**.
2. Next I added a new scaffold item: MVC 5 Controllers with views, using Entity Framework. Note: Success, controllers and views generated

Question
--------

From now on I don't want to use Code First to update my database. Instead I want the models to be updated based on database changes. What to do next? If I don't have an edmx file will I not be able to update my model classes from the database?
