<panel title="Summary">

* EF4 generate a context that derived from ObjectContext and entity classes that derived from EntityObject.
* Starting with EF4.1, MS recommends swapping code generation template that generates a context deriving from DbContext and POCO entity classes.
* In Visual Studio 2012 you get DbContext code generated by default.
    * Existing models will continue to generate ObjectContext based code unless you decide to swap to the DbContext based code generator.
