Something wrong with references using two layers in the Entity

I made an example in Entity 5.0 and with 1 layer worked perfect.

Now I have separated in UI and DA L, but this is giving error. The same page that worked on the DAL layer when done in UI is giving error. I think it's a lack of reference.

The error is:

Server Error in '/' Application.

Source Error: 

Line 41:    using (var ctx = new DAL.TracesEntities())

I made reference to the DAL project and the DLL:

packages\EntityFramework.5.0.0\lib\net45\EntityFramework.dll

I do not remember if I should copy some .tt something to UI to work. Strange that interlisense in UI works perfectly with entity of DAL
