i have simple query.i have searched many times not getting satisfactory result. i want generate diagram entities(code first) , relationship between them.i have total 19 classes far.i have seen articles on reverse engineer code first.but see diagram looks created in database first approach.

so far, have installed entity framework power tools in visual studio 2013 there getting 2 options---

1>reverse engineer code first 2>customize reverse engineer template
